Abstract

γ-ray singles and coincidence measurements following the decay of 2.41-min Ag108 have been performed with Ge(Li) and NaI(Tl) detectors. A total of 13 γ rays have been assigned to Ag108 decay and their energies and intensities have been measured accurately. From the coincidence measurements and energy-sum relationships 12 γ rays have been fitted into six excited states of Pd108 with the following energies in keV and spins: 433.96, 2+; 931.09, 2+; 1052.82, 0+; 1314.22, 0+; 1441.16, 2+; and 1539.97, 1, 2. The first excited 2+ state of Cd108 at 632.98 keV is also populated by the β decay of Ag108. The spins of the 1052.82- and 1314.22-keV levels were determined uniquely as 0 from the NaI(Tl)-Ge(Li) directional-correlation measurements. These data also yield a spin of 2 for the 1441.16-keV level and E2+2% M1 multipolarity for the 1007.22-keV transition. A discussion of the Pd108 levels within the vibrational framework is presented.
