An experiment on neutron-deficient nuclei in the region of doubly magic $^{100}\mathrm{Sn}$ was carried out at the Radioactive Ion Beam Factory (RIBF) at the RIKEN Nishina Center in Japan. $N\ensuremath{\approx}Z\ensuremath{\approx}50$ nuclei were produced following fragmentation of an intense primary $^{124}\mathrm{Xe}$ 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 $\ensuremath{\beta}$-delayed proton emitter decay half-lives, branching ratios and proton energy spectra of nuclei in the region of $^{100}\mathrm{Sn}$ were performed, with improved precision in many cases. New results for the energy spectrum of $^{101}\mathrm{Sn}$ 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 $^{101}\mathrm{In}$ proton separation energy are presented.
