The energy released in the reaction:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{\u2206}}{\mathbf{m}}{{\mathbf{c}}}^{{\mathbf{2}}}}$

The reaction process is:

${}_{\mathbf{1}}^{\mathbf{1}}\mathit{H}\mathbf{\left(}\mathit{p}\mathit{r}\mathit{o}\mathit{t}\mathit{o}\mathit{n}\mathbf{\right)}{\mathbf{+}}_{\mathbf{0}}^{\mathbf{1}}\mathit{n}{\mathbf{\to}}_{\mathbf{1}}^{\mathbf{2}}\mathit{H}$

The reduced mass is obtained from:

$\begin{array}{rcl}\mathbf{\u2206}\mathbf{m}& \mathbf{=}& {\mathbf{m}}_{\mathbf{p}}\mathbf{+}{\mathbf{m}}_{\mathbf{n}}\mathbf{-}{\mathbf{m}}_{{}_{\mathbf{1}}^{\mathbf{2}}\mathbf{H}}\\ & \mathbf{=}& \mathbf{1}\mathbf{.}\mathbf{0072766}\mathbf{+}\mathbf{1}\mathbf{.}\mathbf{0086654}\mathbf{-}\mathbf{2}\mathbf{.}\mathbf{01355}\end{array}$

Consider a fusion reaction in which a proton fuses with a neutron to form a deuterium nucleus. How much energy is released in this reaction? (The mass of the deuterium nucleus is 2.01355u). Answer in *MeV.*
