Question
Calculate the minimum energy needed to separate a neutron from a nucleus with Z protons and N neutrons it terms of the masses $\mathrm{M}_{\mathrm{Z}, \mathrm{N}}, \mathrm{M}_{\mathrm{Z}, \mathrm{N}-1}$ and the mass of the neutron.
✓

Answer

$\text{E}_2\text{N}=\text{E}_{\text{Z,N}-1}+\text{ }^1_0\text{n}.$
Energy released $=($ Initial Mass of nucleus - Final mass of nucleus $) \mathrm{c}^2=\left(\mathrm{M}_{\mathrm{Z}. \mathrm{N}-1}+\mathrm{M}_0-\mathrm{M}_{\mathrm{ZN}}\right) \mathrm{c}^2$.
