what is Muon capture?
86499
Muon capture is the capture of a negative muon by a proton, usually resulting in production of a neutron and a neutrino, and sometimes a gamma photon.\n\nMuon capture by heavy nuclei often leads to emission of particles; most often neutrons, but charged particles can be emitted as well.\n\nOrdinary muon capture (OMC) involves capture of a negative muon from the atomic orbital without emission of a gamma photon:\n\nμ- + p+ → nu + n \nRadiative muon capture (RMC) is a radiative version of OMC, where a gamma photon is emitted:\n\nμ- + p+ → nu + n + γ \nOne motivation for the study of muon capture on the proton is its connection to the proton's induced pseudoscalar form factor gp.\n\nhttp://en.wikipedia.org/wiki/Muon_capture

A sample of the starting element is placed inside a nuclear reactor which produces a lot of neutrons, some of which are absorbed by nuclei in the sample. Different nuclides have different affinities for neutron capture.\n\nPolonium 210 has been in the news lately. It's made via this method from bismuth 209. Bismuth 209 captures a neutron to become bismuth 210 and then quickly emits an electron from the nucleus to become polonium 210.\n\nSome artificial nuclides can be produced by bombarding material with protons or electrons from particle accelerators.\n\nTechnetium 99 is an artificial nuclide that is used in every modern hospital every day for a variety of tests. Te99 is formed from the fission of uranium. It is extracted from spent fuel rods from reactors.

This conversion is done daily at particle accelerators. The problem is that it is exceedingly difficult to produce much matter this way since anti-matter is always produced at the same time and because the energies needed are huge. So you will never seea hunk of matter that was produced this way, you can see the tracks of the particles that have been.

Well, a proton is not an elementary particle.  And the electron is the smallest lepton.  However, an elementary muon will decay to an electron and neutrino when passing from space into an atmosphere

It's the electrostatic repulsion that tends to prevent positively-charged objects from approaching the nucleus.  Most commonly, it's the repulsion that prevents two nuclei from coming into close proximity, and so must be overcome if nuclear fusion is to occur.

A cat is placed in a sealed box. Attached to the box is an apparatus containing a radioactive atomic nucleus and a canister of poison gas. This apparatus is separated from the cat in such a way that the cat can in no way interfere with it. The experiment is set up so that there is exactly a 50% chance of the nucleus decaying in one hour. If the nucleus decays, it will emit a particle that triggers the apparatus, which opens the canister and kills the cat. If the nucleus does not decay, then the cat remains alive. According to quantum mechanics, the unobserved nucleus is described as a superposition (meaning it exists partly as each simultaneously) of "decayed nucleus" and "undecayed nucleus". However, when the box is opened the experimenter sees only a "decayed nucleus/dead cat" or an "undecayed nucleus/living cat." \n\n\nBasically what they are saying is that there could be 2 states at the same time..alive and dead.  There is more at the link below.

The alpha particle is actually the nucleus of a helium atom, it is a positively charged particle. It's to big to penetrate skin. Beta particles are high energy electrons or positrons, they can penetrate skin and cell membranes but not the whole body (as X rays do).\n    \nThe positive charge of alpha particles is useful in some industrial processes. For example, radium-226 may be used to treat cancer, by inserting tiny amounts of radium into the tumorous mass.\n\nPositron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination based on the detection of radiation from the emission of positrons.\nPET scans are used to detect cancer and to examine the effects of cancer therapy by characterizing biochemical changes in the cancer. These scans can be performed on the whole body. PET scans of the heart can be used to determine blood flow to the heart muscle and help evaluate signs of coronary artery disease. PET scans of the heart can also be used to determine if areas of the heart that show decreased function are alive rather than scarred as a result of a prior heart attack, called a myocardial infarction. Combined with a myocardial perfusion study, PET scans allow differentiation of nonfunctioning heart muscle from heart muscle that would benefit from a procedure, such as angioplasty or coronary artery bypass surgery, which would reestablish adequate blood flow and improve heart function. PET scans of the brain are used to evaluate patients who have memory disorders of an undetermined cause, suspected or proven brain tumors or seizure disorders that are not responsive to medical therapy and are therefore candidates for surgery.\n\nGamma particles are capable to penetrate skin and the body, too. They are high energy electromagnetic waves that kill living cells. In nuclear medicine, a drug incorporating a gamma-ray emitting radio-nuclide is administered to the patient and the desired organ is imaged by tracing the distribution or flow of the radio-nuclide by scanning the patient with a gamma-ray camera. Radiotherapy is used exclusively in the treatment of malignant tissue to kill cancerous cells. Beams of high energy x-rays or gamma-rays from cobalt-60 sources are most commonly used for such purposes.

What kind of detector?

The first answer was good and it will allow you to capture exactly what you see on your monitor, however it'll grab not just what you're looking at, but everything else on your desktop too.  To just capture the active window, press:\n\nALT+PRT SCR and then you can paste it into whatever (Paint, E-Mail, Word, etc).\n\nGood luck!

I'm not sure in what context these terms are being used for the situation you are trying to understand.\n\nPhysicists often use collimated beams of neutral or charged particles to study the reaction or interaction of those particles with other particles.  A common experiment involves two beams of particles that are set up to cross each other, and the zone of overlap forms an "interaction region" in which the interactions between the particles in the two beams can be studied.  If the particles interact in either chemical or nuclear reactions, those reactions would be called "beam-beam reactions".\n\n"Beam-background reactions" are reactions between the particles in the beam and particles that are present in "the background", rather than particles in the other beam.  The background might be residual gas molecules in a high-vacuum chamber, or particles in a plasma for a beam-beam fusion experiment.  Basically, they are the "noise" in the experiment that must be accounted for because they are not usually the source of the signal one is trying to measure.

I cannot tell you whether or not it has been done...\nBut I will never be truly "trapped" even with a mirror with a fairly high finish (aka 1-2 microns) there is still a loss every time it "bounces" off the mirror + if you do not do it in a vacuum there will be atomspheric losses as well.\nHenceforth if it is "trapped" it wouldn't stay there for long..

These are sensors that can detect radioactivity and have uses in security devices and other security devices.\nAll elements are stable under normal conditions , but some elements like uranium and plutonium are less stable than the others . When the atoms of these substances are disturbed (its called excited state) they emit energy in the form of radioactivity . This radio activuty can be detected by these sensors .

Electron-positron annihilation is the process that occurs when an electron (which is matter) and a positron (which is antimatter) collide. If they are both relatively at rest (which happens in an exotic but not uncommon form of matter called positronium), they destroy each other upon contact, and produce two gamma ray photons of 511 keV each which are emitted in opposite directions. If they are moving at different relative velocities, the energies of the photons emitted will be higher, in accordance with the conservation of momentum. [At higher relative velocities, other particle-antiparticle pairs can also be produced, since there is enough kinetic energy in the relative velocities to provide for the masses of those particles. At much higher relative velocities, there may be enough energy to produce a single neutral Z-boson. The opposite process is known as pair production or matter creation.]\n\nOf course, both the electron and the positron cease to exist, as their masses are converted to energy (E = mc^2), which is the energy of the two resultant photons.\n\nThere is no separate law of conservation of matter (or, mass). Actually, it goes together with the law of conservation of energy, under the name 'mass-energy conservation'. And this conservation of mass-energy, as well as the conservation of momentum, both hold during the process of annihiltion.

Read Angels and Demons. Although the antimatter making technique is totally impractical, it just might be possible to store the stuff in a hand-grenade sized container. Magnetic suspension has already been done, although it would make a large hand grenade with current technology.\nhttp://www.levitron.com/\n\nA truly perfect vacuum really is impossible, but a near-perfect vacuum could be done. Just as long as you eliminate all the gas molecules floating around, you should be safe enough. http://www.physlink.com/Education/AskExperts/ae290.cfm
