Problem

Calculate the energy released, in MeV, when a single deuterium nucleus combines with a tritium nucleus to form a helium-4 nucleus and a free neutron. Atomic masses • deuterium: 2.014102 u2.014102\,\text{u} • tritium: 3.016049 u3.016049\,\text{u} • helium-4: 4.002603 u4.002603\,\text{u} • neutron: 1.008665 u1.008665\,\text{u} Take 1 u↔931 MeV/c21\,\text{u} \leftrightarrow 931\,\text{MeV}/c^2.
