Abstract
Large-scale shell-model calculations have been performed to calculate the negative-parity states of even-odd 61−65Fe isotopes. The results are compared with the recent experimental data reported at Legnaro National Laboratories and also with earlier calculations with fpg interaction in a truncated configuration space. It is observed that negative parity states of 61Fe can be well reproduced with GXPF1A interaction in full fp space without truncation. For 63Fe the correct ordering of levels is not reproduced. The structure of the wave function for the ground state and first excited state suggests that the ordering of the single-particle energy levels gets modified due to monopole correction.
