Description
The CREX-PREX dilemma involving the weak form factors of calcium-48 and lead-208 challenges models that tie neutron skins to the symmetry energy. We explore a resolution by artificially enhancing the isovector spin-orbit interaction in relativistic mean-field models. This adjustment brings theoretical predictions into agreement with experiment by modifying the neutron distribution in calcium, while leaving lead largely unaffected. However, it disrupts spin-orbit shell structure and magic numbers, suggesting that although promising, this approach may not be the full solution.
