“…The two-hole calculation on 56Fe gives a rather good spectrum which is similar to previous shell-model calculations [2,9,[21][22][23] within the same space 9 An important and unexpected result from the present three-hole calculation is that for both interactions all states in 56Fe contain about 40~o admixtures of (fv/2) -3 components i.e. there is no decrease with respect to S4Fe and 5SFe (see also Sect.…”

Extensive shell-model calculations have been performed on 5'*'55'56Fe. The results obtained in a model space with two and with up to three f7/2 holes in the 56Ni core are compared with experiment. The Surface Delta Interaction (SDI) and the Kuo Brown interaction (KB) have been used to calculate energy levels, spectroscopic factors and electromagnetic properties resulting especially for 56Fe in a remarkably good agreement with experiment. Admixtures of three-hole components in the wave functions are significant and increase with mass number. Properties of high-spin states with J <15 are discussed. Pronounced collective features derived microscopically are expected in 56Fe. Finally some suggestions for interesting experiments are given.

Shape coexistence in the light krypton isotopes was studied in two low-energy Coulomb excitation experiments using radioactive 74 Kr and 76 Kr beams from the SPIRAL facility at GANIL. The ground-state bands in both isotopes were populated up to the 8 + state via multi-step Coulomb excitation, and several non-yrast states were observed. Large sets of matrix elements were extracted for both nuclei from the observed γ -ray yields. Diagonal matrix elements were determined by utilizing the reorientation effect. In both isotopes the spectroscopic quadrupole moments for the ground-state bands and the bands based on excited 0 + 2 states are found to have opposite signs. The experimental data are interpreted within a phenomenological two-band mixing model and model-independent quadrupole invariants are deduced for the relevant 0 + states using the complete sets of matrix elements and the formalism of quadrupole sum rules. Configuration mixing calculations based on triaxial Hartree-Fock-Bogolyubov calculations with the Gogny D1S effective interaction have been performed and are compared both with the experimental results and with recent calculations using the Skyrme SLy6 effective interaction and the full generator-coordinate method restricted to axial shapes.

“…A leading concern with using Coulomb excitation to extract accurate electromagnetic moments is the role of Coulomb-nuclear interference on the measured cross sections, which is destructive near the barrier [15,17,18]. Table I …”
