Abstract
Very neutron-deficient Bi-191,Bi-193 nuclei have been studied at the Depart ment of Physics, University of Jyvaskyla, Finland (JYFL) employing the Juro sphere II Ge-detector array coupled to the gas-filled recoil separator RITU and different tagging techniques. For the first time in heavy odd-mass nuc lei, a collective band (oblate) is identified above the 2p-1h (1/2(+)) prot on intruder state in Bi-191. In both Bi-191,Bi-193, a band based on isomeri c 13/2(+) state has been observed and oblate deformation for this state has been deduced.
