Abstract.

High-spin states of the 44Sc nucleus, populated in the 68 MeV 18O + 30Si reaction, have been studied in a γ-γ-recoil coincidence experiment. The detailed decay pattern, with various paths and cross-transitions, has been extended up to 9.1 MeV. High-quality DCO and polarization information assign spins and parities for the majority of the observed levels. The negative-parity states are discussed and compared with rotational bands in neighbouring f7/2-shell nuclei.
