The Decay of Ag-105g

The level structure of Pd-105 has been studied from the decay of Ag-105g. The energies and intensities of 50 gamma rays have been precisely measured using a 64.1 c.c. Ge(Li) detector (FWHM=2.1 keV at 1.33 MeV). The gamma ray singles spectrum measurements confirm the existence of the 158.93, 167.5, 202.17, 216.11, 382.5, 486.65, 576.64, 583.01, 844.34, 860.20, 921.23, 929.01 and 1124.90 keV gamma rays in the decay of Ag-105g. However, the 270.5, 564.39, 580.13, 610.0, 640.5, 709.8, 768.9 and 796.25 keV weak transitions reported by earlier workers could not be observed in the present investigations. Also the γ-γ directional correlation coefficients for 7 cascades in Pd-105 have been measured. Out of these, the 361-(447)-280 and 807-280 keV cascades have been attempted for the first time. From these correlation measurements spin value of 1/2+ has been confirmed for the 673.03 keV level. Also these measurements have been used to deduce the multipole mixing ratios of seven transitions in Pd-105.
