New μs isomers in Tz=1 nuclei produced in the 112Sn(63A MeV)+natNi reaction

Abstract

The short-lived isomeric states in the $T_Z$=1 nuclei, ${}^{94m}$Pd $[T_{1/2}$=0.6(1) $\mu$s] and ${}^{96m}$Ag $[T_{1/2}$=0.7(2) $\mu$s], were identified among the fragmentation products of the ${}^{112}$Sn $(63A$ MeV) + ${}^{\mathrm{nat}}$Ni (93.5 mg/cm${}^2)$ reaction at GANIL. The separation and identification of the reaction products was done by means of the Alpha and LISE3 magnetic spectrometers combined with time-of-flight, energy-loss, and total kinetic energy measurements. Evidence for isomeric states in ${}^{80}$Y, ${}^{98}$Cd, and ${}^{102}$Sn was also obtained.
