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 `""_(20)^(41)ca` and `""_(13)^(27)` Al from the following data `m(""_(20)^(40)Ca)=39.962591 u`
` m( ""_(20)^(40)Ca ) = 39.962591 u`
`m( ""_(20)^(41)Ca ) = 40.962278 u`
` m( ""_(13)^(26) Al ) = 25.986895 u`
`m( ""_(13)^(27) Al ) = 26.981541 u`
