Abstract Shell model calculations in the lower fp shell region, (for 44,45Ca and 47Sc nuclei) have been performed, with different model spaces, to probe the effect of configuration mixing from the p3/2, p1/2 and f5/2 orbitals on the predominantly (f7/2)n states and the contribution arising from the excitation of the N = Z = 16 core. Our calculations indicate that excitation of nucleons across the N = Z = 16 magic shell closure do contribute significantly towards the wavefunctions of the observed level structures of 44,45Ca nuclei. However the inclusion of these configurations did not result in a better agreement for the observed level structure of 47Sc nulcei. A plaussible explaination for this phenomena could be attributed to the two-body matrix elements used and calls for a detailed micro-scopic calculations involving fundamental interactions substantiated by additional spectroscopic data such as lifetime measurements to have an unambigious understanding of the intrinsic configurations of nuclei in this region.
