“…Earlier measurements [21] were made with poor resolution on natural copper, making it difficult to separate the contributions from the transition to (2+)1 in 62Ni and that to the 64Ni ground state. The results here are consistent with the assumption of equal population made in [21] which is also what would be expected from the spectroscopic factor C2S=0.7 for transitions to the 64Ni ground state [37,38]. [21] also suggests that members of the 0 +, 2 +, 4 + triplet are populated in the [7, P)-reaction but this is not verified in the present work.…”

“…Mairle et al [38] and Blair and Armstrong [39] disagree regarding the amount of fp=l pick-up. The (d, 3He)-results indicate a 58Ni ground state with a very small P3/2 proton admixture as shown in the weak {p= 1 pick-up to the (3/2-)1 state in 57Co at 1.38MeV (Ep=7.89MeV), while the (t, c0-reaction also shows a stronger #p=l transition to (3/2)2 at 1.76 MeV (Ep = 7.52 MeV) and therefore imply a larger P3/2 admixture.…”

Abstract.Earlier work has shown how information about the giant dipole resonance and proton hole states can be inferred from high resolution photoproton spectra obtained in irradiation with the 17.62 MeV gamma quanta produced by the ~Li(p, 7)SBe-reaction. To exploit this method the high energy photoproton spectra from 45Sc, 51V, 59Co, 5SNi, 63Cu and natural nickel have been measured with 60-120 keV resolution. The absolute cross sections for transitions to levels in the daughter nucleus have been determined. The results are compared with a simple model assuming a semidirect reaction proceeding via a dipole doorway state. Good correlation is found between the cross sections and the spectroscopic factors measured in proton pick-up reactions. Comparison with the total photoproton cross section for 5SNi indicates, however, that the majority of protons are emitted at lower energies from more complicated states.
