Abstract.

Levels in 115Pd and 117Pd nuclei, populated in the spontaneous fission of 248Cm were studied by means of prompt gamma spectroscopy using the EUROGAM2 array of Anti-Compton spectrometers. Negative-parity, I = 9/2 excitations were identified, which are associated with the long-lived isomers in these nuclei, reported previously as 11/2- excitations. The new data indicate spin and parity 3/2+ for ground states in 115Pd and 117Pd instead of 5/2+ proposed in previous works. This result implicates changes of spin assignments to other levels in both nuclei.
