Role of dynamic pairing correlations in fission dynamics. II. Fermium and nobelium isotopes

The competition between the quenching of pairing due to repulsive Coulomb interaction and dynamic correlations added by particle number symmetry restoration has been studied in a selected set Fermium Nobelium isotopes using hierarchy Hartree-Fock-Bogoliubov--based approximations restricted variation after projection, all them based on $\mathrm{D}1{\mathrm{M}}^{*}$ parametrization Gogny force. It is found that antipairing partially compensated beyond-mean-field correlations. However, compensation not perfect modulation spontaneous fission half-lives, as functions neutron number, indicates combined effect dynamics cannot be overlooked. Neither can it accounted for Slater approximation.
