Hartree-Fock approximation for deformed nuclei with a general two-nucleon potential and pairing correlations with a consistent residual interaction.

DD Dao - 2019 - theses.hal.science
In this work, we have developed the Hartree-Fock (HF) approximation in momentum space
for deformed nuclei with a general nucleon-nucleon (NN) potential. The structure of such a …
