Shell evolution and isomers below 132Sn: Spectroscopy of neutron-rich 46Pd and 47Ag isotopes

Neutron-rich isotopes of Pd (Z = 46) and Ag (Z = 47) have attracted considerable interest in terms of the evolution of the N = 82 shell closure and its influence on the r-process nucleosynthesis. Such previously unreachable exotic nuclides have become accessible by means of in-flight fission of a high-intensity 238U beam available at a new-generation radioactive isotope (RI) beam facility, the RI Beam Factory (RIBF) in RIKEN Nishina Center. In this report, recent spectroscopic results of Pd and Ag isotopes obtained as part of the EURICA (EUROBALL-RIKEN Cluster Array) project at RIBF are presented
