Gamma production and inferred level cross sections for inelastic neutron scattering from ^159Tb
Abstract
Differential gamma-ray production cross sections for the ^159Tb (n,n'γ) reaction were measured at 125^o for incident neutron energies in the 375- to 975-keV range. Neutron level cross sections were inferred from the measurements. Thin (50 keV) metallic lithium targets were used to generate neutrons via the ^7Li(p,n)^7Be reaction at the UML Van de Graaff accelerator. A Ge detector was used in conjunction with the pulsed beam time-of-flight technique to observe gamma decays. A NaI(Tl) annulus was used to suppress signals caused by Compton scattered gamma rays.
