Elastic and Inelastic Scattering of Protons from Nickel Isotopes; Ni⁵⁸ and Ni⁶⁰, in the Energy Range from 7.0 MeV to 15.3 MeV

Angular and energy dependence of the elastic and the inelastic scattering of protons from nickel isotopes, Ni 58 and Ni 60 , were investigated in the energy range from 7.0 MeV to 15.3 MeV. Angular distributions in the high energy region ( E p ≥10 MeV) showed small difference between both isotopes. Energy dependence of the differential cross sections in the low energy region (7 MeV< E p <9 MeV) showed some fluctuations both for the elastic and the inelastic scattering. The inelastic yield for Ni 58 was larger than that for Ni 60 in the low energy region ( E p ≤9 MeV). These yields decreased gradually as the incident energy increased. The results of present work are compared with our previous one and with the investigations of Thirion et al., Greenlees et al., and Seward.
