BETA (MINUS) DECAY

Physics

BETA (MINUS) DECAY

1. THE NEUTRON BECOMES A PROTON BY LOOSING ITS NEGATIVE CHARGE.

2. A neutron decays into => a proton + negatron + anti-neutrino.

3. Occurs in radionuclides with a neutron excess. Radionucleids produced by nuclear fission are usually neutron-rich.

4. Beta particles are identical to ordinary electrons.

5. The antineutrino is an electrically neutral subatomic particle. The absence of charge and the infinitesimal mass of antineutrinos make them very difficult to detect.

6. Any excess energy in the nucleus after beta (minus) decay is emitted as gamma rays, internal conversion electrons, and other associated radiations.
