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,
