Abstract
Beta decay of a refractory isotope $\ensuremath{\mathsf{^{118}Rh}}$ produced in symmetric fission and mass separated by the ion guide technique has been applied for the study of low-lying excited states of $\ensuremath{\mathsf{^{118}Pd}}$ . The yrast band in $\ensuremath{\mathsf{^{118}Pd}}$ has been observed up to a 6⁺ state and the lowest states of the asymmetric $\gamma$ -band have been identified. The measured half-life of $\ensuremath{\mathsf{^{118}Rh}}$ is $(300\pm60)$ ms. The systematics of the excited states in neutron-rich $\ensuremath{\mathsf{Pd}}$ -isotopes implies the saturation towards an O(6)symmetry at N=70.
