Title: Probing sd-fp cross-shell interactions via terminating configurations in {sup 42,43}Sc

Abstract

An experimental study of the lower fp-shell nuclei {sup 42,43}Sc was performed via {alpha}pn and {alpha}p evaporation, respectively, from {sup 20}Ne + {sup 28}Si and {sup 24}Mg + {sup 24}Mg fusion-evaporation reactions. The experiments were conducted with the Gammasphere and Microball detector arrays. The level schemes of both nuclei have been extended considerably. Terminating states associated with the f{sub 7/2}{sup n} and d{sub 3/2}{sup -1}f{sub 7/2}{sup n+1} configurations were identified in each nuclide and incorporated into detailed comparisons with neighboring nuclei and with shell model calculations. The energy differences between the terminating states provide a test of the sd-fp cross-shell interactions in these calculations.
