Abstract

The structure of 210Fr has been studied through the 197Au(18O, 5n)210Fr reaction. A high-spin iso-meric state has been identified at ∼4.4 MeV. It has a lifetime of 686(17) ns and decays by two γ-rays that are very likely to be either M2 or E3 multipolarity. The measured strengths in the case of E3 assignments are ap-proximatively 8 and 21 W.u., respectively. These would be less enhanced than is observed in the decay from the high spin isomers in 209Fr and 211Fr that are believed to be from a related configuration. Possible configuration assignments are discussed.
