Özet

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.
