Problem

The masses of a proton, neutron and a

^4_2\text{He}

nucleus are

m_p = 1.0073\,\text{u}

,

m_n = 1.0087\,\text{u}

and

m_{\text{He}} = 4.0015\,\text{u}

respectively. Using

1\,\text{u}=931\,\text{MeV}/c^{2}

, the binding energy per nucleon of

^4_2\text{He}

is closest to a)

28\,\text{MeV}

b)

14\,\text{MeV}

c)

7.1\,\text{MeV}

d)

6.5\,\text{MeV}
