\(\underset{\text { Deuterium }}{^2 _1 H}+\underset{\text {Tritium}}{{ }_{1}^{3} H } \longrightarrow \underset{{\text {Helium}}}{^{4} He} +\underset{neutron}{^1_0n} +Q\)

The energy released in the process is given by

\(Q=\left[M_{^{2}_{1} H}+M_{^{3}_{1} H}-M_{^{4}_{2} H e}-M_{^1_0n}\right] c^{2}\)

\(\;\;\;=[2.014102+3.016050-4.002603-1.008665] u c^{2}\)

\(\;\;\;=(0.018884 u)\left[931.5 \frac{ MeV }{u}\right]=17.6 \;MeV\)
