Define beta `(beta)` decay.

Define beta decay?

Define gamma (gamma) decay.

What is the basic mechanism for the emission of beta^(-) or beta^(+) particles in a nucleide? Give an example by writing explicity a decay process for beta^(-) emission. Is (a) the energy of the emitted beta -particles continuous or discrete, the daughter nucleus obtained through beta -decay, an isotope or an isobar of the parent nucleus?

Write symbolically the process expressing the beta^+ decay of _(11)Na^(22) Also write the basic nuclear process underlying this decay.
