Question

A nuclear decay is possible if the mass of the parent nucleus exceeds the total mass of the decay particles. If M (A, Z) denotes the mass of a single neutral atom of an element with mass number A and atomic number Z, then the minimal condition that the β decay

XZAYz+1A+β+Ve

will occur is (me denotes the mass of the β particle and the neutrino mass mv can be neglected):
