Neutron-Induced Partial Gamma-Ray Cross-Section Measurements on Uranium at TUNL*

Precision measurements of (n,n') and (n,2n) reaction cross sections have been performed on $^{235,238}$U targets at Triangle Universities Nuclear Laboratory using a pulsed and monoenergetic neutron beam. The excitation function has been studied with incident neutron energies between 5 and 14 MeV and beam flux of 10$^{4}$ n s$^{-1}$ cm$^{-2}$ at target position. Multiple partial cross sections have been determined observing gamma rays in clover and planar HPGe detectors. The results will be compared with calculations using Hauser-Feshbach model.
