Question:

The inelastic scattering threshold energies for the first two levels in ${ }^{232} \mathrm{Th}$ are 50 and $160 \mathrm{keV}$, respectively. Calculate the reaction $Q$-values for these levels.

$\Delta=M-A$ 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.
