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

Precision measurements have been performed on $^{235,238}$U targets at Triangle Universities Nuclear Laboratory using a and monoenergetic neutron beam. The excitation function of (n,2n) reaction has been studied with incident energies between 5 and 15 MeV and beam flux of 104 n s$^{-1}$ cm$^{-2}$ at target position. Multiple (n,n') and (n,2n) partial cross sections have been measured using clover and planar HPGE detectors in this energy range, and results will be compared with the Hauser-Feshbach model. A more in-depth explanation of the techniques and analysis will be presented.
