Question

Write the basic nuclear process underlying β⁺ and β^– decays.

Answer 1

Basic process underlying β+ and β− decay are
During a weak interaction an atomic nucleus converts into a  nucleus with one higher atomic number while emitting one electron and an electron antineutrino this is called beta minus decay.

`X_Z^A->Y_(Z+1)^A+e^(-)+ bar(v_e)`

During a weak interaction an atomic nucleus converts into a nucleus with one lower number while emitting a positron and electron neutrino this is called  beta Plus decay.

`X_Z^A->Y_(Z-1)^A+e^(+)+v_e`
