DECAY OF 1.2 MIN 113MAG AND 5.3 H 113GAG

The decay schemes of 1.2 min and 5.3 h 113Ag have been studied using Ge(Li) and NaI(Tl) detectors and a 4096-channel multiparameter pulse-height analyser system. The decay of 5.3 h 113Ag was found to involve 15 γ-rays and to produce 10 excited states in 113Cd at energies of 264.7, 298.0, 315.6, 583.9, 604.6, 681.1, 883.6, 936.9, 989.0 and 1195.2 keV. The italicized energies refer to negative parity states, through which 1.3% of the decays go to yield the 14y111mCd ( 11 2-) isomer at 264.7 keV. The 604.6 keV level is thought to be a case|9/2- level similar for those found in several odd-mass Te and Xe isotopes. The 1.2 min 113mAg decay was found to populate several of the same levels in Cd and two additional levels at 452 and 689 keV. The 1.2 min 113Ag is the upper isomer with high spin, probably 7 2+. © 1969.
