A nucleus ZXA emits 9α-particles and 5p particle. The ration of total protons and neutrons in the final nucleus is:-
Show that the minimum energy needed to separate a proton from a nucleus with Z protons and N neutrons is △E=(Mz−1,N+MH−MZ,n)C2 Where MZ,n= mass of an atom with Z protons and N neutrons in the nucleus and MH= mass of a hydrogen atom. This energy is known as proton-separation energy.
