Beta-decay measurement for the A=130 r-process abundance peak

ORAL

Abstract

A new generation of radioactive ion beam facilities, such as the Radioactive Ion Beam Factory (RIBF) at the RIKEN Nishina Center for Accelerator Based Science in Japan, have extended the reach of nuclear physics experiments to isotopes near or at the path of the r-process. This will provide, in the near term, a wealth of new nuclear data essential to improve the reliability of r-process nucleosynthesis models. We present the recent work of the BRIKEN collaboration to measure decay half-lives and beta-delayed neutron emission probabilities of very neutron-rich isotopes at RIBF [1,2]. In particular, we will discuss preliminary results for an experiment in the region of Rh to Cs [3], which are progenitors of the A=130 r-process abundance peak.
