β -decay of neutron-rich nuclei with Z ≈ 60 : The origin of rare-earth elements

Abstract : A large fraction of the rare-earth elements around A = 160 observed in the solar system are produced in the astrophysical rapid (r-) neutron-capture process. However, current stellar models cannot completely explain the relative abundance of these elements partially because of nuclear physics uncertainties. To address this problem, a b -decay spectroscopy experiment was performed at RI Beam Factory (RIKEN), aimed at studying a wide range of very neutron-rich nuclei with Z ¼ 60. This experiment provides a test of nuclear models as well as experimental inputs for r-process calculations
