Ab initio reproduction of absolute nuclear charge radii

Develop ab initio nuclear theory capable of accurately reproducing the absolute magnitudes of nuclear charge radii, particularly for medium- and heavy-mass isotopes where correlations and shell effects are significant.

Background

Charge radii reflect detailed nuclear structure and are highly sensitive to inter-nucleon interactions, making them particularly challenging for first-principles approaches.

The paper highlights that despite progress, quantitatively matching the magnitude of measured charge radii with ab initio theory is unresolved, underscoring a key target for improving microscopic interactions and many-body methods.
