Question

The mass of deutron ${(}_1{H}^2)$ nucleus is $2.013553$ a.m.u. If the masses of proton and neutron are $1.007275$ a.m.u. and $1.008665$ a.m.u. respectively, calculate the mass defect, the packing fraction , binding energy and binding energu per nucleon.

Answer 1

Mass defect $=$ Mass of atom $-$ Mass of neutron and proton

Mass defect $=2.013553-(1.007275+1.008665)=0.002387$

Binding Energy $=0.002387\times 931=2.22MeV$

Binding Energy per nucleon $=\frac{2.22}{2}=1.11MeV$
