Spectroscopy of exotic $^{123,125}$Ag produced in fragmentation reactions

We extended the experimental knowledge in the mass-region around $^{132}$Sn by identifying the decay of high-spin isomers in the exotic odd-mass $^{123,125}$Ag. The two isotopes were produced at the NSCL laboratory by projectile fragmentation of a $^{136}$Xe beam at 120MeV/u directed onto a thick Be target. The NSCL Beta Counting System was used identify the secondary beam fragments. Prompt and delayed gamma-rays following the deexcitation of the fragments were detected with the SEGA array. Partial level schemes for $^{123,125}$Ag are proposed for the first time and compared with the results of shell-model calculations.
