For the reaction 01n+24He  →  13H+12H_0^1\text{n}+{}_2^4\text{He}\;\rightarrow\;{}_1^3\text{H}+{}_1^2\text{H} the atomic masses are 01n=1.008665 u,24He=4.002603 u,_0^1\text{n}=1.008665\,\text{u},\quad {}_2^4\text{He}=4.002603\,\text{u}, 13H=3.016049 u,12H=2.014102 u._1^3\text{H}=3.016049\,\text{u},\quad {}_1^2\text{H}=2.014102\,\text{u}. The reaction is endothermic. If the helium nucleus is initially at rest, determine the minimum kinetic energy that the incident neutron must possess for the reaction to occur. Choose the closest value. (a) 17.6 MeV17.6\,\text{MeV} (b) 4.4 MeV4.4\,\text{MeV} (c) 22 MeV22\,\text{MeV} (d) 35.2 MeV35.2\,\text{MeV}
