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.
