Abstract

Low-lying levels of100Rh have been investigated with the reaction100Ru(p, nγ)100Rh in the proton energy range 4.4 MeV≦E p≦6 MeV.

A level scheme including 18 previously unreported excited levels has been deduced on the basis of singlesγ spectra and extensiveγ-γ coincidence measurements. Theγ branchings of several levels have also been measured. By means of the pulsed beam technique, the mean lifetimes of the excited states at 151.8, 160.7, 329.4 and 389.7 keV have been determined asτ m=(1.4±0.2)ns, (5.7±0.3)ns, (1.1±0.4)ns and 0.9±0.4)ns, respectively. The lifetimes of the levels at 32.7 keV and 74.8 keV have been found to beτ m=(36.5±4.5) ns and (312.5±7.5) ns, in good agreement with recently reported values. An upper limit of 0.5 ns has also been placed for the lifetimes of eleven other levels.
