Abstract

The lifetime and branching ratio of the 19+ isomer in 210At have been measured. Its enhanced E3 decay and g-factor, and those of the related 39 2- isomer in 211At are compared with the results of a semi-empirical shell model calculation which includes couplings to the 3- octupole vibration, resulting in mixed configurations. Lifetimes were also obtained for the 15- isomer in 210At, and the 29 2+ isomer in 209At.
