Neutron configurations inPd113

Abstract

Excited states in113 Pd, 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 113 Pd, proposed recently at 166.1 keV by other authors, have 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+ band head has been proposed at 151.9 keV. A possible oblate-shape origin of these low-energy bands heads has been discussed.

“…The present work extends results on 107 Mo obtained from measurements of prompt γ rays following fission, collected using large arrays of Ge spectrometers, with new data on lowspin excitations, obtained from measurement of γ radiation following the β − decay of monoisotopic samples of 107 Nb. Both types of data complement each other, as demonstrated earlier [24][25][26]. The measurement of the β − decay of 107 Nb, performed for the first time, revealed new transitions and excited levels in 107 Mo, in particular, establishing a new, 1/2 + ground state of 107 Mo.…”

“…Both techniques were used to trace transitions towards an oblate shape in 110 Mo and 111 Tc utilizing either the EUROGAM2 array for triple-γ study [3,4] or the Penning-trap separation technique [5]. The effect was also searched for using the Penning-trap technique at A = 113 [6], 115 [7], and 117 [8].…”
