Question:

If the initial energy of the neutron is $2 \mathrm{MeV}$, find the maximum energy loss to the elastically scattered neutron in ${ }^{2} \mathrm{H},{ }^{56} \mathrm{Fe}$, and ${ }^{238}\mathrm{U}$. $\Delta=M-A$ is the "mass excess," where $M$ is the mass of a nuclide and $A$ its mass number. These data are given in the Nuclear Wallet cards, and elsewhere. The data given below may be useful in solving some of the problems.
