Find the ratio of a narrow SLBW resonance cross-section at a neutron energy (E=E_{0}+n Gamma), to that

Question:

Find the ratio of a narrow SLBW resonance cross-section at a neutron energy $E=E_{0}+n \Gamma$, to that at the peak, $n$ being an integer. Calculate the ratio when $n=2$. $E_{0}$ is the resonance energy and $\Gamma$ is the total width.

$\Delta=M-A$ 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.
