Levels In Cd-125 Populated By The Beta Decay Of (125)Mag And Ag-125

The beta decay of Ag-125m,Ag-125 into levels in Cd-125 was investigated at the Holifield Radioactive Ion Beam Facility (HRIBF). Uranium-238 targets were bombarded with 50-MeV protons with an intensity of 15 mu A, and the induced fission products were mass separated and deposited on a moving tape in the center of the VANDLE array consisting of gamma detectors and plastic scintillators. A partial decay scheme has been assigned for both beta decay of the (9/2(+)) ground state of Ag-125 and its low-lying (1/2(-)) isomer, with the energy of the low-lying (11/2-) isomeric state in Cd-125 assigned as 188.5 keV. In addition, beta-delayed neutron emission probabilities were also determined to be 1.2(2)% for the (9/2(+)) Ag-125 ground state and 4.6(10)% for the (1/2(-)) isomer, which are substantially lower than the previously reported value.
