Distinguish between nuclear fission and fusion. Show how in both these processes energy is released. Calculate the energy release in MeV in the deuterium-tritium fusion reaction :
$_{1}H+_{1}H→_{1}He+_{0}n_{1}$
Using the data:
$m(_{1}H)=2.014102u$
$m(_{1}H)=3.016049u$
$m(_{2}He)=4.002603u$
$mn=1.008665u$
