Abstract Integral cross sections of the reactions 46 Ti( n , p ) 46 Sc, 47 Ti( n , p ) 47 Sc, 48 Ti( n , p ) 48 Sc, 60 Ni( n , p ) 60 Co and 64 Zn( n , p ) 64 Cu 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 46 Ti( n , p ) 46 Sc reaction where JEFF-3.2 shows a deviation of 7% and the 60 Ni( n , p ) 60 Co reaction where ENDF/B-VII.0 and IRDF-2002 exhibit deviations upto 8%.
