Hi dear,

Repulsion between protons within the nucleus leads to larger ratios of neutron to proton , for stable nucleii for increasing mass numbers.

Neutron deficit nucleii would undergo alpha decay to increase their  N/Z ( neutron to proton) ratios.

The energy converted from mass energy to kinetic energy is called the Q value which is shared between nucleus and the alpha particle abiding the law of conservation of momentum.

Packing fraction is a measure of stability of a nucleus ={( mass defect ) X 10⁴ }/ mass number.

Hope this satisfies your quetion.

Regards,

Aruna
