Abstract
This UNNS note reports on the recent precision spectroscopy of the radioactive molecule 225RaF, which resolves the effect of the nuclear magnetization distribution on its hyperfine structure — the Bohr–Weisskopf correction in a molecule. In τ-Field language, this is the first resolved signature of recursion curvature inside a nuclear chamber: a finite-thickness τ-boundary within the 225Ra nucleus that imprints itself on electronic energy levels. We reinterpret the experiment as a direct probe of τ-Field microstructure and show how its results align with the UNNS picture of curvature, torsion, and symmetry violation in strongly deformed nuclei.
