Question

Solution

Correct option is

8.363 MeV

When a neutron is separated from , we are left with , that is,    This is the total mass of the remaining atom and the separated neutron. The mass of the initial atom was 40.962278 u. Therefore, the mass defect is Its energy equivalent is = 8.363 MeV.

This is the neutron separation energy.
