Abstract

An experiment on neutron-deficient nuclei in the region of doubly magic ¹⁰⁰Sn was carried out at the Radioactive Ion Beam Factory (RIBF) at the RIKEN Nishina Center in Japan. N ≈ Z ≈ 50 nuclei were produced following fragmentation of an intense primary ¹²⁴Xe beam and implanted in the Advanced Implantation Detector Array silicon setup for the first study of proton-rich nuclei with this system at RIKEN. Measurements of the β-delayed proton emitter decay half-lives, branching ratios and proton energy spectra of nuclei in the region of ¹⁰⁰Sn were performed, with improved precision in many cases. New results for the energy spectrum of ¹⁰¹Sn are presented, where a 2.03(5)-MeV peak was observed. These results are compared to shell-model calculations, using the recent precise measurement of the ¹⁰¹In proton separation energy are presented.
