Total Neutron Cross Sections of Chlorine and Carbon

Using C${\mathrm{Cl}}_4$ in good geometry, ${\mathrm{Li}}^7(p, n)$ neutrons and a pressurized hydrogen counter, ${\sigma }_t\left(\mathrm{Cl}\right)$ has been measured by the transmission method from 0.4 to 1 Mev at 30-kev intervals and from 0.15 to 0.75 Mev at 2-kev intervals.
