Abstract:

Giant multipole resonances and bound states above 6 MeV in Ni 60 were studied with inelastic scattering of electrons at 102 MeV incident energy and scattering angles of 60, 75, 90, and 105 degrees. In the energy interval from 5 MeV to 40 MeV excitation energy, ten states and resonances were observed of which only those below 7 MeV and those at 16.5 and 18.5 had been previously reported. Reduced transition probabilities were calculated, and multipolarity assignments were made. The ten transitions were observed at excitation energies of 6.1 E3,E2, 7.0 E3,M2, 7.6 E2,E3,M2, 8.4 E2,E0, 9.9 E1, 11.8 E2,E0 , 12.9 E3,M2, 15.0 E4, 16.5 E2,E0, and 18.5 E1 MeV. The E4 resonance at 15.0 MeV was previously unreported. The E2 resonance at 16.5 MeV reported in alpha, alpha primed work and the E1 resonance at 18.5 MeV from Gamma,n were confirmed.
