Configuration mixing of angular-momentum and particle-number projected triaxial HFB states using the Skyrme energy density functional

Understand

We present a method based on mean-field states generated by triaxial quadrupole constraints which are projected on particle number and angular momentum and mixed by the generator coordinate method on the quadrupole moment.

• This method is equivalent to a seven-dimensional GCM calculation, mixing all five degrees of freedom of the quadrupole operator and the gauge angles for protons and neutrons.
• A first application to Mg24 permits to analyze in detail the effects of triaxial deformations and of K-mixing.
