abstract

  • Radioactive 97Rh was produced via the 96Ru(p,γ)97Rh reaction. The two most intense lines in the γ-ray spectrum of 97Rh, at 190 and 421 keV, were observed to decay with half-lives of 40 ± 2 and 30 ± 2 min respectively. This result is interpreted as evidence for a 30 min isomeric state in 97Rh. The interpretation is further supported by the observation of the 19 keV Rh Kα X ray. With this interpretation it is possible to resolve a discrepancy in the observations of previous investigators as regards the relative intensity of the 190 and 421 keV transitions.
