Abstract

The reaction 103Rh(p, nγ)103Pd at incident proton energies between 1.4 and 6.3 MeV has been used to excite the levels in 103Pd and to study their subsequent γ-decay. In-beam singles, anti-Compton, and γ-γ coincidence measurements have been made using Ge(Li) detectors, a NaI(Tl) annulus, and an on-line multi-parameter data acquisition system. By these methods more than 40 γ-rays associated with 103Pd as well as γ-γ coincidence spectra gated by 18 separate γ-transitions were observed. Excited states at 118.9, 243, 266, 294, 504, 531, 625, 698, 716, 726, 884, 900, 913, 1042, 1068, 1183 and 1277 keV were identified by these measurements. The triplet of states at 697-716-726 and 884-900-913 keV had not been resolved by previous experiments. Probable spin and parity assignments are suggested for some of the levels. Branching ratios are determined along with a decay scheme for 103Pd.
