The spectra and electromagnetic transitions of the odd-odd nucleus Sc-
52 are calculated in the nuclear shell model approach, using the full
fp shell basis functions with no truncation. Two of the most used two-
body effective interactions in the fp shell yield quite different nucl
ear spectra. The energy levels from the two interactions are compared,
as well as the magnetic and quadrupole moments and the electromagneti
c transitions. The available experimental data, mostly 1(+) levels, ar
e not sufficient to conclude which interaction provides a better fit.
