Abstract

A very high spin isomeric state with m=34(3) s has been observed at an excitation energy of 8.5 MeV in Fr212. The experimental evidence favors an E3 assignment, with a very large E3 transition strength, B(E3)=100(12)×103 e2fm6, to one of the rays de-exciting the isomer. The observed properties are in very good agreement with the characteristics of a 34+ state predicted by the multiparticle octupole vibration model.
