115RH C {+115}Ru produced in 25-MeV proton-induced fission of uranium
115RHaC followed by mass separation at IGISOL-JYFLTRAP facility. The |g rays
115RHaC were detected by three Ge detectors, a planar Ge detector (LOAX) and
115RHaC a plastic scintillator for |b radiation. Measured E|g, I|g, |g|g,
115RHaC |b|g, (x ray)|g coin
115RH C Level scheme is from 2011Ri07. Levels up to 696 were also reported in
115RHaC 2007Ku06, and up to 1258 in 2010Ku01
115RH C All data are from 2011Ri07, unless otherwise stated
115RH CB $By comparison the total |b feeding to states in {+115}Rh with that
115RHaCB to |b feeding of states in {+115}Pd in {+115}Ru --> {+115}Rh -->
115RHaCB {+115}Pd decay chain, 2011Ri07 find that 6% {I6} of the |b feeding
115RHaCB from {+115}Ru is unaccounted. One possibility is that the 76-ms
115RHaCB isomer found in 2010Ku25 partly decays by |b decay which may also
115RHaCB explain small |b feeding of (7/2+) state at 617.6
115RH CB LOGFT$2011Ri07 state that all log| {Ift} values should be considered
115RHaCB as lower limits since there is possibility of missing high-energy
115RHaCB low-intensity |g rays from high-lying levels allowed by large Q(|b)
115RHaCB window.
115RH CG $A 61.7-keV |g ray is seen in singles |g spectrum in 2010Ku01, but
115RHaCG not in |b-gated spectrum. Its half-life was measured as 76 ms {I14}.
115RHaCG In a further study, 2010Ku25 assigned this an isomer in {+115}Ru
