description

Very neutron-deficient Bi-191,Bi-193 nuclei have been studied at the Department of Physics, University of Jyvaskyla, Finland (JYFL) employing the Jurosphere II Ge-detector array coupled to the gas-filled recoil separator RITU and different tagging techniques. For the first time in heavy odd-mass nuclei, a collective band (oblate) is identified above the 2p-1h (1/2(+)) proton intruder state in Bi-191. In both Bi-191,Bi-193, a band based on isomeric 13/2(+) state has been observed and oblate deformation for this state has been deduced. ispartof: Acta Physica Polonica B vol:32 issue:3 pages:1019-1023 ispartof: location:POLAND, ZAKOPANE status: published
