Abstract
Results are presented to 550 keV of high resolution time of flight neutron total cross section measurements using various sample thicknesses of natural calcium. An $R$-matrix analysis was made to fit the results for the nine strong $s$ levels in $^{40}\mathrm{Ca}$ above 100 keV. A transmission area analysis was made for the 22 weaker observed levels which are also mainly due to $^{40}\mathrm{Ca}$, but have $l>0$. We obtain $10^{4}\mathrm{S}_{0}=({2.97}_{\ensuremath{-}1.05}^{+1.95})$ for $^{40}\mathrm{Ca}$.NUCLEAR REACTIONS $^{40}\mathrm{Ca}(n,n)$, ($n,\ensuremath{\gamma}$), $E=0\ensuremath{-}550$ keV; measured ${\ensuremath{\sigma}}_{t}(E)$; deduced ${E}_{0}$, ${\ensuremath{\Gamma}}_{n}$, ag ${\ensuremath{\Gamma}}_{n}$, ${S}_{0}$.
