“…Summing over all isoscalar excitations with energy up to 24 MeV, one finds that most of the sum rule is exhausted: 75.0% for L=0 and 90.5% for L=2. The scattering experiments [2] show a peak which extends from 13 to 18 MeV. The calculated energies and widths of both multipole resonances are thus compatible with the experimental data.…”

“…The calculated energies and widths of both multipole resonances are thus compatible with the experimental data. Satchler [2] carried out a DWBA calculation of the differential cross section for the excitation of the monopole as well as the quadrupole mode. For the normalization of the curves he assumed the maximum transition strength allowed by the sum rules, The differential cross section was measured in the energy region 14.6-16,7 MeV.…”

Abstract. Estimates of the excitation energy, width and sum rule fraction of the collective monopole and quadrupole vibrations indicate that the peak in the 62 A -~/3 MeV region is a superposition of the 0 + and 2 + modes.Experiments on the inelastic scattering of electrons and protons on various target nuclei [-1] have shown a giant resonance with energy around 62 A -1/3 MeV. Angular distributions were consistent with either a 0 + or a 2 + assignment. The form factors of the two multipolarities were found to differ from each other when the beam was polarized. Therefore new experiments have been performed on Ni 5s using a polarized proton beam [-2]. In order to identify this giant resonance we present calculations of the collective 0 + and 2 + vibrations in Ni 58 and compare them with experiment.
