We report on the preliminary results from a study of the decay of the I\pi =8+ T1/2 =2 \mu s isomer in 96Pd performed as part of the Stopped-Beam RISING campaign within the Rare Isotope Investigation at GSI (RISING). The 96Pd ions were produced following the projectile fragmentation of a 750 MeV per nucleon 107Ag primary beam. The reaction products were separated and identified by the in-flight method using the GSI Fragment Separator. The residues of interest were stopped in a perspex stopper surrounded by an array of 15, seven-element germanium Cluster detectors. One of the goals of the current work is to investigate the population of high-spin states produced projectile fragmentation reactions using isomeric ratio measurements to infer information on the angular momentum population distribution. In this short contribution the method and results of determining the isomeric ratio for the I\pi = 8+ microsecond isomer in 96Pd nucleus are presented.
