Mean-field studies of time reversal breaking states in super-heavy nuclei with the Gogny force

Abstract

Recent progress on the description of time reversal breaking (odd mass and multi-quasiparticle excitation) states in super-heavy nuclei within a mean field framework and using several flavors of the Gogny interaction is reported. The study includes ground and excited states in selected odd mass isotopes ofnobelium and mendelevium as well as high K isomeric states in 254No. These are two and four-quasiparticle excitations that are treated in the same self-consistent HFB plus blocking framework as the odd mass statesThis work has been supported in part by the MINECO (Spain) grants Nos. FPA2012-34694 and FIS2012-34479, and by the Consolider-Ingenio 2010 program MULTIDARK CSD2009-0006
