For the fusion reaction

^{2}_{1}\text{H}+^{3}_{1}\text{H}\;\rightarrow\;^{4}_{2}\text{He}+^{1}_{0}\text{n}

, calculate the energy released per reaction event in MeV. Atomic masses:

^{2}_{1}\text{H}=2.0141\,\text{u}

^{3}_{1}\text{H}=3.0160\,\text{u}

^{4}_{2}\text{He}=4.0026\,\text{u}

^{1}_{0}\text{n}=1.0087\,\text{u}

Take

1\,\text{u}=931.5\,\text{MeV}/c^{2}

. (a)

14.0\,\text{MeV}

(b)

1.76\,\text{MeV}

(c)

17.6\,\text{MeV}

(d)

10.4\,\text{MeV}
