Problem

Using the atomic mass data:

^{3}_{1}\mathrm H: 3.016\,\text{u}

^{2}_{1}\mathrm H: 2.014\,\text{u}

^{4}_{2}\mathrm He: 4.003\,\text{u}

^{1}_{0}\mathrm n: 1.009\,\text{u}

, calculate the energy released (Q-value) in MeV for the fusion reaction

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

. (Use

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

.) (a)

20.4\,\text{MeV}

(b)

15.0\,\text{MeV}

(c)

17.6\,\text{MeV}

(d)

13.6\,\text{MeV}
