Full fp shell calculation of 52Sc

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 nuclear spectra. The energy levels from the two interactions are compared, as well as the magnetic and quadrupole moments and the electromagnetic transitions. The available experimental data, mostly 1(+) levels, are not sufficient to conclude which interaction provides a better fit.
