COLLECTIVE HIGH-SPIN STATES IN SC-45

The high-spin states in Sc-45 were studied with the GASP multidetector array. The nuclei were excited by the Si-30(O-18,p2n)Sc-45 reaction a t E(LAB)=60 MeV and separated with the Recoil Mass Spectrometer. Sever al new high-spin levels extending the known single-particle and collec tive structures were observed. Energies of the negative-parity states agree with the shell model predictions whereas the positive-parity-int ruder rotational band extends up to very high rotational frequencies a nd continues beyond the maximum angular momentum available from the si ngle-particle f(7/2) configuration.
