Integral cross section measurements of a few threshold reactions induced by Am/Be neutrons

Abstract

Abstract Integral cross sections of the reactions 46Ti(n, p)46Sc, 47Ti(n, p)47Sc, 48Ti(n, p)48Sc, 60Ni(n, p)60Co and 64Zn(n, p)64Cu were measured with fast neutrons (E n  > 1.5MeV) from an Am/Be source. The results were compared with data calculated using the neutron spectral distribution and the excitation function of each reaction given in the data libraries ENDF/B-VII.0, IRDF-2002, JEFF-3.2 and JENDL-4.0. In general, the integral measurement and the integrated value agreed within ±4%, except for the 46Ti(n, p)46Sc reaction where JEFF-3.2 shows a deviation of 7% and the 60Ni(n, p)60Co reaction where ENDF/B-VII.0 and IRDF-2002 exhibit deviations upto 8%.
