摘要：
This contribution summarizes an experiment performed at GSI (Germany) in the neutron-rich region beyond N= 126. The aim of this measurement is to provide the nuclear physics input of relevance for r-process model calculations, aiming at a better understanding of the third r-process abundance peak. Many exotic nuclei were measured around Hg-211 and Tl-215. Final ion identification diagrams are given in this contribution. For most of them, we expect to derive halflives and and beta-delayed neutron emission probabilities. The detectors used in this experiment were the Silicon IMplantation and Beta Absorber (SIMBA) detector, based on an array of highly segmented silicon detectors, and the BEta deLayEd Neutron (BELEN) detector, which consisted of 30 He-3 counters embedded in a polyethylene matrix.
