Abstract
Low-lying spectra and several high-spin states of odd-even 61,63,65Co isotopes are calculated in two different shell-model spaces. First set of calculations have been carried out in fp-shell valence space (full fp space for 63,65Co and a truncated one for 61Co) using two recently derived fp-shell interactions, namely GXPF1A and KB3G, with 40Ca as core. Similarly, the second set of calculations have been performed in fpg 9/2 valence space using an fpg effective interaction due to Sorlin et al., with 48Ca as core and imposing a truncation. It is seen that the results of GXPF1A and KB3G are reasonable for 61,63Co. For 65Co, shell-model results show that the fpg interaction adopted in the study is inadequate and also points out that it is necessary to include orbitals higher than 1g 9/2 for neutron-rich Co isotopes.
