Spallation neutron production by 0.8, 1.2, and 1.6 GeV protons on various targets -: art. no. 044621

Spallation neutron production in proton induced reactions on Al, Fe, Zr, W, Pb, and Th targets at 1.2 GeV and on Fe and Pb at 0.8 and 1.6 GeV measured at the SATURNE accelerator in Saclay is reported. The experimental double differential cross sections are compared with calculations performed with different intranuclear cascade models implemented in high energy transport codes. The broad angular coverage also allowed the determination of average neutron multiplicities above 2 MeV. Deficiencies in some of the models commonly used for applications are pointed out.
