    Abstract

    The Ru-113 and Rh-113 nuclei, produced in the spontaneous fission of Cm-248 and in proton-induced fission of U-238; were studied by means of prompt gamma spectroscopy using the EUROGAM 2 array of Anti-Compton spectrometers and the IGISOL mass separator, respectively. For the 0.5 s isomer, found in (RU)-R-113 in our recent study we propose the 7/2- [523] configuration. The present data indicate spin and parity 1/2(+) for the ground state in Ru-113. This and some new data on the excited levels in Rh-113 allows reinterpretation and a better Understanding of the beta(-) decay scheme of Ru-113. The properties of Ru-113 were studied in the frame of the Core-Quasiparticle Coupling model, which has well reproduced the experimental data.
