Description
We establish a universal baseline for the widths of near-threshold single-neutron resonances in L>0 partial waves. The baseline arises from discrete scale invariance at zero energy in the finite square-well potential and depends only on geometry, angular momentum, and resonance energy. Comparison with data shows that it provides a robust benchmark, while deviations caused by Woods-Saxon diffuseness reveal structure-dependent effects.
