Title: Commissioning of the BRIKEN detector for the measurement of very exotic β -delayed neutron emitters

Abstract

A new detection system has been installed at the RIKEN Nishina Center (Japan) to investigate decay properties of very neutron-rich nuclei. The setup consists of three main parts: a moderated neutron counter, a detection system sensitive to the implantation and decay of radioactive ions, and -ray detectors. We describe here the setup, the commissioning experiment and some selected results demonstrating its performance for the measurement of half-lives and β-delayed neutron emission probabilities. Here, the methodology followed in the analysis of the data is described in detail. Particular emphasis is placed on the correction of the accidental neutron background.
