Status and results from the decay spectroscopy project EURICA (Euroball-RIKEN Cluster Array)

摘要

β- and isomer-decay spectroscopy are sensitive probes of nuclear structure, and are often the only techniques capable of providing data for exotic nuclei that are produced with very low rates. Decay properties of exotic nuclei are also essential to model astrophysical events responsible for the evolution of the universe such as the rp- and r-processes. The EURICA project (EUROBALL RIKEN Cluster Array) has been launched in 2012 with the goal of performing spectroscopy of very exotic nuclei. Since 2012, five experimental campaigns have been successfully completed using fragmentation of ~(124)Xe beam and in-flight-fission of ~(238)U beam. In these proceedings we will introduce the experimental setup and highlight some key recent results around ~(78)Ni, ~(132)Sn, and ~(110)Zn published during 2014 and 2015.
