Decay of the neutron-rich isotope {^113} Rh
The decay of neutron-rich isotope Ru obtained
as on-line mass separated product of proton-induced fission has
been investigated by coincidence and
spectrum multiscaling measurements. Decay schemes for both low- and
high-spin isomers of Ru have been constructed. The level
scheme of 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 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 feeding is
found to populate high-lying levels in Rh. The GT strength
in Ru decay is significantly larger than for the decay
of Ru and of lighter rhodium isotopes
