Problem

Two deuterium nuclei fuse according to

^2_1\mathrm D + ^2_1\mathrm D \rightarrow ^3_2\mathrm{He} + n

. Given atomic masses

^2_1\mathrm D = 2.014102\,\text{u}

^3_2\mathrm{He} = 3.016029\,\text{u}

n = 1.008665\,\text{u}

, and

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

, calculate the energy released per fusion reaction. a)

6.54\,\text{MeV}

2.27\,\text{MeV}

3.27\,\text{MeV}

3.02\,\text{MeV}
