Problem

A capture reaction is given by

^{12}_{\;6}\mathrm{C}+^{1}_{0}\mathrm{n}\;\rightarrow\;^{13}_{\;6}\mathrm{C}+\gamma.

Using the atomic masses

^{12}\mathrm{C}=12.000000\,\text{u}

^{1}\mathrm{n}=1.008665\,\text{u}

^{13}\mathrm{C}=13.003355\,\text{u}

, calculate: (i) the Q-value of the reaction in MeV, (ii) whether the reaction is exothermic or endothermic. Take

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