Decay of the neutron-rich isotope 113Ruto{^113} Ru to {^113} Rh

The decay of neutron-rich isotope $^{113}$Ru obtained as on-line mass separated product of proton-induced fission has been investigated by $\gamma\gamma$ coincidence and spectrum multiscaling measurements. Decay schemes for both low- and high-spin isomers of $^{113}$Ru have been constructed. The level scheme of $^{113}$Rh is considerably extended. Systematics of the lowest-lying rhodium levels is smooth. The picture of shape coexistence established for neutron-rich Rh isotopes near-neutron midshell is confirmed with the observation of a $K=1/2$ deformed band, with its 3/2$^+$ state at 600 keV being the lowest-lying level and of probable 7/2$^+$ and 5/2$^+$ band members. A large fraction of $\beta$ feeding is found to populate high-lying levels in $^{113}$Rh. The GT strength in $^{113}$Ru$^{\rm m}$ decay is significantly larger than for the decay of $^{113}$Ru$_{\rm g}$ and of lighter rhodium isotopes
