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,
