Measurement of High Energy Neutron Induced Cross Sections for Chromium

Reaction cross sections for Cr induced by neutrons at 287 MeV were measured by using Li-7(p,n) reaction at NO beam line in the Research Center for Nuclear Physics (RCNP), Osaka University. To estimate quasi-monoenergetic neutron-induced cross sections, the Cr sample was irradiated on the two angles of 0 degrees and 30 degrees for the axis of the primary proton beam. Proton-induced reaction cross sections for Cr at 300 MeV were also measured. The measured cross section data in the Cr-nat(n,x) and Cr-nat(p,x) reactions are compared with the literature values and the JENDL high-energy file. Furthermore, those in the Cr-nat(n,x) reactions are also compared with those in the Cr-nat(p,x) reaction.
