0Beta particle is a high energy, high speed electron or positron emitted in the radioactive decay of an atomic decay of an atomic nucleus, such as a potassium - 40 nucleus.
The positron or antielectron is the antiparticle or the antimatter counterpart of the electron.
- The positron has an electric charge of +1 e, a spin of 1/2(same as electron).
- A positron has the same mass as an electron.
- Lets solve an example:
