Abstract
The 𝛽 decay of 125𝑚,125Ag into levels in 125Cd 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 125Ag and its low-lying (1/2−) isomer, with the energy of the low-lying (11/2−) isomeric state in 125Cd assigned as 188.5 keV. In addition, 𝛽-delayed neutron emission probabilities were also determined to be 1.2(2)% for the (9/2+) 125Ag ground state and 4.6(10)% for the (1/2−) isomer, which are substantially lower than the previously reported value.
