how do alpha and beta particles behave in a magnetic field?

A magnetic field (only one pole is shown) affects radioactive rays differently depending on the type of ray. Alpha rays (heavy, positively charged particles) are deflected slightly in one direction. Beta rays (light, negatively charged electrons) are deflected strongly in the opposite direction.

Beta particle emission occurs when the ratio of neutrons to protons in the nucleus is too high. In this case, an excess neutron transforms into a proton and an electron. The proton stays in the nucleus and the electron (-1) is ejected energetically.

Beta radiation consists of high-energy electrons emitted from the nucleus. These electrons have not come from the electron shells or energy levels around the nucleus. Instead, they form when a neutron splits into a proton and an electron.

Alpha particles don't travel very fast (compared with beta particles) because they have such a large mass. ... Alpha particles are deflected slightly in a magnetic field. Their large mass means that they don't get deflected much.

In gamma decay, only energy, in the form of gamma rays, is emitted. Alpha and beta decay occur when a nucleus has too many protons or an unstable ratio of protons to neutrons. When the nucleus emits a particle, it gains or loses one or two protons, so the atom becomes a different element.

The alpha particle is a helium nucleus; it consists of two protons and two neutrons. It contains no electrons to balance the two positively charged protons. Alpha particles are therefore positively charged particles moving at high speeds. ... Beta particles are negatively charged.

Alpha particles are positively charged, beta particles are negatively charged, and gamma radiation is electrically neutral . This means that alpha and beta radiation can be deflected by electric fields , but gamma radiation cannot. ... Just as with electric fields, gamma radiation is not deflected by magnetic fields.

Alpha particle. ... Alpha particles, like helium nuclei, have a net spin of zero. Due to the mechanism of their production in standard alpha radioactive decay, alpha particles generally have a kinetic energy of about 5 MeV, and a velocity in the vicinity of 5% the speed of light.

Beta Particles in an electric field Beta particles are attracted to the positively charged plate. This confirms that they are negatively charged. Beta particles are fast moving electrons with a very low mass and so have a high charge to mass density. They are deflected much more than the heavier alpha particles.

Alpha particles are released by high mass, proton rich unstable nuclei. The alpha particle is a helium nucleus; it consists of two protons and two neutrons. ... Beta particles are emitted by neutron rich unstable nuclei. Beta particles are high energy electrons.

Alpha particles are subatomic fragments consisting of two neutrons and two protons. Alpha radiation occurs when the nucleus of an atom becomes unstable (the ratio of neutrons to protons is too low) and alpha particles are emitted to restore balance.

In alpha decay, shown in Fig. 3-3, the nucleus emits a 4He nucleus, an alpha particle. ... An alpha particle, with its two protons and two neutrons, is a very stable configuration of particles. Alpha radiation reduces the ratio of protons to neutrons in the parent nucleus, bringing it to a more stable configuration.

Magnetic fields deflect the motion of particles possessing a net electrical charge. When such charged particles encounter a magnetic field they experience something called the "Lorentz Force," which is directed at right angles to both the magnetic lines of force and the direction of motion of the particle.

An alpha-particle is identical to the nucleus of a normal (atomic mass four) helium atom i.e. a doubly ionised helium atom. Alpha particles (also termed alpha radiation or alpha rays) was the first nuclear radiation to be discovered, beta particles and gamma rays were identified soon after.

Alpha radiation is the name for the emission of an alpha particle in fact an helium nuclei, beta radiation is the emission of electrons or positrons , and gamma radiation is the term used for the emission of energetic photons.
