IDENTIFICATION OF EXCITED-STATES IN CE-125

Excited states have been identified in neutron-deficient Ce-125(58)67 using the Ni-58(Ge-70,2pn)Ce-125 reaction at 280 and 310 MeV. The expe riment was performed at the Holifield Radioactive Ion Beam Facility, O ak Ridge National Laboratory. A gamma-ray array of six clover plus fou r single-crystal HPGe detectors was used in conjunction with the Recoi l Mass Spectrometer, which had a position sensitive avalanche counter (mass A identification) at its focal plane, together with an ionizatio n chamber (charge Z identification). Two band structures assigned to C e-125 are interpreted as based on the nu h(11/2)[523]7/2(-) and nu d(5 /2)[402]5/2(+) Nilsson orbitals, respectively.
