It is found that if a neutron suffers an elastic collinear collision with deuterium at rest, fractional loss of its energy is $\displaystyle \mathrm{p}_{\mathrm{d}}$; while for its similar collision with carbon nucleus at rest, fractional loss of energy is $\displaystyle \mathrm{p}_{\mathrm{c}}$. The values of $\displaystyle \mathrm{p}_{\mathrm{d}}$ and $\displaystyle \mathrm{p}_{\mathrm{c}}$ are respectively :
