COLLECTIVE HIGH-SPIN STATES IN THE LIGHT ODD F7 2 NUCLEI/

The high-spin states in (SC)-S-45, Ti-45 and Ca-43 were studied with t he GASP multidetector array coupled with the Recoil Mass Spectrometer in Legnaro. The nuclei were excited in the Si-30 + 60 MeV O-18 reactio n. Lifetimes were extracted from the analysis of the Doppler shift att enuation of gammas emitted in the reversed kinematics C-12 + Cl-35 rea ction. Energies and the transition probabilities for the observed nega tive-parity states agree with the shell model predictions. The lifetim es of the intruder-positive parity states in (SC)-S-45 and Ti-45 sugge st a deformation (beta approximate to 0.25) associated with the partic le-hole excitation in the nuclei.
