Following the irradiation of a rhodium chloride target with 35-MeV protons from LBNL's 88-Inch Cyclotron, we chemically separated the rhodium and palladium fractions and then counted them separately using high-purity Ge detectors. In the Rh fraction, we clearly see a growth over time in the intensities of several gamma-ray lines attributable to the decay of Rh-102. One possible interpretation of these results is that there exists a previously unknown second isomer in Rh-102. From our measurements, we deduce a half life of this potential new isomer of approximately 46 hours. Puzzles associated with these observations will be discussed.

Another isomer in Rh102?
