Abstract

The β decay of Ag125m,125 into levels in Cd125 was investigated at the Holifield Radioactive Ion Beam Facility (HRIBF). Uranium-238 targets were bombarded with 50-MeV protons with an intensity of 15μA, and the induced fission products were mass separated and deposited on a moving tape in the center of the VANDLE array consisting of γ detectors and plastic scintillators. A partial decay scheme has been assigned for both β decay of the (9/2+) ground state of Ag125 and its low-lying (1/2-) isomer, with the energy of the low-lying (11/2-) isomeric state in Cd125 assigned as 188.5 keV. In addition, β-delayed neutron emission probabilities were also determined to be 1.2(2)% for the (9/2+) Ag125 ground state and 4.6(10)% for the (1/2-) isomer, which are substantially lower than the previously reported value.
