Physical Review C vol:69 issue:3 pages:-
Excited levels in Se-69 have been studied using the Ca-40(S-32,2pn)Se-69 reaction at 95- and 105-MeV beam energy. gamma rays have been detected with the EUROBALL spectrometer operated in conjunction with the neutron wall and the charged-particle detector array EUCLIDES. New level sequences with positive and negative parities have been identified from n-gammagamma and n-gammagammagamma coincidences. Spins have been assigned to many of the levels on the basis of angular distribution and directional correlation measurements. Excitation energies of the positive-parity yrast band and the branching ratios of its decay are compared with the predictions of the rigid triaxial rotor plus particle model.
