Beyond Mean-Field Calculations for Odd-A Nuclei

Understand

Beyond mean-field methods are very successful tools for the description of large-amplitude collective motion for even-even atomic nuclei.

• The state-of-the-art framework of these methods consists in a Generator Coordinate Method based on angular-momentum and particle-number projected triaxially deformed Hatree-Fock-Bogoliubov (HFB) states.
• The extension of this scheme to odd-mass nuclei is a long-standing challenge.
• We present for the first time such an extension, where the Generator Coordinate space is built from self-consistently blocked one-quasiparticle HFB states.
