In a recent ref. [1] group representation methods have been applied to the nuclear point-group symmetries and combined with realistic mean-field calculation results together with the new specifically designed methods of experimental analysis. The authors demonstrated that existing in the literature experimental data on 152Sm are fully compatible with the extremely restrictive group-theory...
Exploiting exact and special symmetries to unmask simplicity within complexity, which remains the ‘holy grail’ of nuclear physics, will be considered within its historical context and as evolving through 21st Century ‘ab initio’ methods, including emerging results linked to the internal structure of nucleons.
Some exemplar results for very light to medium mass nuclei will be presented, and...
Pairing correlation produces the odd-even staggering of the binding energies.
In addition to that, it also introduces spontaneous breaking of the gauge symmetry.
The pairing rotation is the Nambu-Goldstone mode associated with the gauge symmetry breaking
in superconducting nuclei, and is measurable experimentally as a pairing rotational band.
In our previous work [1], it was shown that the...
A new Skyrme functional devised to account well for standard nuclear properties as well as for spin and spin-isospin properties is presented. The main novelty of this work relies on the introduction of tensor terms guided by ab initio relativistic Brueckner-Hartree-Fock calculations of neutron-proton drops. The inclusion of tensor term does not decrease the accuracy in describing bulk...
