New Levels in ¹¹⁸Pd Observed in the β Decay of Very Neutron-Rich ¹¹⁸Rh Isotope

We investigate the β decay of very neutron-rich ¹¹⁸Rh isotope using on-line mass-separated sources which are produced by applying 25MeV proton induced symmetric fission of natural uranium at the IGISOL facility. The β--γ and γ--γ coincidence spectroscopy is employed to establish the level scheme of daughter nucleus ¹¹⁸Pd. Five low-lying new levels are identified for the first time with tentative spin and parity assignments based on the even-mass Pd systematics.
