Understanding the Effect of Chiral NN Parametrization on Nuclear Shapes from an Ab Initio Perspective
Paper in proceeding, 2025
The ab initio symmetry-adapted no-core shell model naturally describes nuclear deformation and collectivity, and is therefore well-suited to studying the dynamics and coexistence of shapes in atomic nuclei. For the first time, we analyze how these features in low-lying states of6Li and12C are impacted by the underlying realistic nucleon-nucleon interaction. We find that the interaction parametrization has a notable but limited effect on collective shapes in the lowest6Li and12C states, while collective structures in the excited 2+ state of12C are significantly more sensitive to the interaction parameters and exhibits emergent shape coexistence.
