An experimental study of the lower fp-shell nuclei 42,43Sc was performed via αpn and αp evaporation, respectively, from 20Ne + 28Si and 24Mg + 24Mg 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 f7/2n and d3/2-1f7/2n+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.
