A systematic study was performed of microsecond γ-decaying isomers around ¹⁰⁰Sn produced in a fragmentation reaction of a ¹²⁴Xe beam at 345 MeV/u at the Radioactive Ion Beam Factory of the RIKEN Nishina Center in Saitama, Japan. Half-lives of isomeric states in that region were remeasured allowing us to improve the currently available experimental information. Reduced transition probabilities were deduced and compared to shell-model calculations in various model spaces. Furthermore, the recently reported low-energy transitions in ⁹²Rh and ⁹⁶Ag were remeasured with improved precision. Additionally, experimental information on isomeric ratios, including five new ones, were extracted and compared to a previous experimental study and the sharp cutoff model of fragmentation reaction.
