Absolute Cross Sections of Proton Induced Reactions on 65Cu, 64Ni and 63Cu

Absolute cross sections have been measured for (p, y) reactions on 63CU, 64Ni and 63CU over proton energy ranges of 1,05-3 '25, 1·00-3 ·45 and 1·05-4· 70 MeV respectively, for (p, n) reactions over proton energy ranges from threshold to 3· 25,3' 80 and 4·86 MeV respectively, and for 63CU(p, p')63CU over a proton energy range of 1·05-4'00 MeV. All the data are compared with global statistical model calculations. The agreement, to within a factor of 2, between theory and experiment is regarded as satisfactory for a global code, but the 64Ni data are suggestive of a closed shell effect at Z = 28.
