G-Factors in 210Rn and octupole coupling of core-excited states in 210Rn, 211Rn and 212Rn

Abstract

The g-factors of isomeric states in 210Rn have been measured using the TDPAD technique. Semi-empirical shell-model calculations, with explicit inclusion of the couplings to the 3 −octupole vibration, are carried out for the core-excited states in 210Rn and 211,212Rn. The resulting mixed multi-particle configurations are used to explain simultaneously the g-factors and enhanced E3 transitions which connect several pairs of these states.
