A spectroscopic study is performed for high spin states of SSFe, 55Co and 57Ni. To populate the investigated residues with a relevant cross section, the fusion evaporation reactions of 3~ 2p n) 55Fe ' 3osi(28Si ' 2 rip) 5SCo and 4He(S4Fe, n) 57Ni were chosen.To identify the new 7 transitions and to build the energy level schemes, 7-7 coincidence techniques together with excitation functions were employed. Angular distributions and 7-7 angular correlations allowed us to assign the spin values of the nuclear states. The previous level scheme of 5SFe is extended into the region between 6.5-11 MeV of excitation energy, up to spin 27/2, while the yrast decay paths of 57Ni and SSCo are reported here for the first time. Experimental data are fairly well reproduced by Glaudemans' shell model calculations.

“…The excitation energies of some high-spin states not shown in Figs. These states, however, are most probably two-hole states, since they are excited in the 54Fe(~, nT) reaction and not in single-neutron pickup reactions on SSNi [12]. For S TNi only the lowest three states can be described with a closed 56Ni core.…”

The influence off 7/2 hole configurations on properties of57?59Ni

1979

View full text Add to dashboard Cite

Shell-model calculations have been performed on 57-59Ni" All configurations with one hole in the f7/2 orbit have been included exactly. The results of a newly proposed approximation method are in good agreement with those of the exact calculations, when applied to the predominant zero-hole states. The experimental results are compared with those of the realistic Kuo-Brown interaction and the schematic St~rface Delta Interaction.The role of the f5/2 orbit differs significantly for these two interactions. The results show that f7/2 hole contributions strongly improve the description of the Ni isotopes.
