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

Abstract: 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 of nobelium and mendelevium as well as high K isomeric states in 254 No. These are two and four-quasiparticle excitations that are treated in the same self-consistent HFB plus blocking framework as t… Show more

“…At the mean field level only a few nuclei in the actinide and rare earth regions are octupole deformed. The number of nuclei accessible increases substantially if the intrinsic state is determined in the variation after parity projection scheme, irrespective of whether it is implemented exactly or in a restricted variational space Robledo 2015b). Octupole correlations are better described using the generator coordinate method with the octupole moment as one of the collective coordinates (Bernard et al 2016, Bucher et al 2017and Bernard et al 2017.…”

“…This is only pos- sible for a few octupole deformed nuclei in the actinide and rare earth regions, if only mean field intrinsic states and the projection after variation scheme are used. The number of nuclei accessible increases substantially if the intrinsic state is determined in the variation after projection scheme, irrespective of whether it is implemented exactly or in a restricted variational space (Robledo, 2015b;Robledo and Bertsch, 2011b). Another possibility is to perform a generator coordinate method calculation using the octupole degree of freedom as one of the collective coordinates.…”

“…Finally, the time-odd sector of the density dependent part of the interaction has never been explored. It is true that the time-odd fields obtained from the central, spin-orbit and Coulomb part lead to a nice reproduction of observables like moments of inertia [79,24,80], spin and parities of the ground state of odd mass nuclei [81,80] or even the excitation energy of high-K isomeric states [82]. However, there are indications in the physics of odd-odd nuclei that additional time-odd fields could be required [83] in order to reproduce the rich phenomenology associated to these kind of nuclei.…”
