The neutron separation energy is defined as the energy required to remove a neutron from the nucleus. Obtain the neutron separation energies of the nuclei ⁴¹₂₀Ca and ²⁷₁₃Al from the following data:

m(⁴⁰₂₀Ca) = 39.962591 u

m (⁴¹₂₀Ca) = 40.962278 u

m (²⁶₁₃Al) = 25.986895 u

m (²⁷₁₃Al) = 26.981541 u

Given that,

We know that,

Removal of one neutron from leads to the formation of ,

The mass defect of this reaction is,

We have, 1 u = 913.5 MeV/c²

Hence the energy required to remove neutron removal,

We know that,
