Fast neutron scattering from cesium

A study was made of the(n, n), (n, n′) and (n, n′ γ) reactions which occur when a cesium scattering sample is exposed to mono-energetic neutrons of energies ranging from 120 to 1910 keV. Total cross sections, elastic scattering angular distributions and excitation functions for inelastic scattering were measured with a neutron time-of-flight spectrometer. Results are compared with statistical theory. A 40 cc Ge(Li) detector was used in the time gated mode to measure γ-rays from the (n, n′ γ) reaction. These data were used to refine and extend the energy level scheme derived from the neutron spectroscopy measurements and mainly confirm the results of recent, similar measurements.
