Write the Basic Nuclear Process Underlying β+ and β– Decays - Physics

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

Solution

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
