Abstract

Excited states in 113Pd, populated in β− decay of 113 Rh and in spontaneous fission of 248 Cm and 252 Cf, have been studied by means of γ spectroscopy at the IGISOL facility of Jyväskylä University and using large arrays of Ge detectors (Eurogam2 and Gammasphere, respectively). The position of the 11/2− yrast excitation in 113Pd, proposed recently at 166.1 keV by other authors, has been corrected to 98.9 keV. The decay of this level has been discussed to explain the observed transition intensities. The 7/2− member of the yrast, unique-parity configuration has been identified at 84.9 keV and a band on top of this level proposed. On top of the 1/2+, first excited state a band has been built and a new 3/2+ bandhead has been proposed at 151.9 keV. A possible oblate-shape origin of these low-energy bandsheads has been discussed.
