Phase-shift parametrization and extraction of asymptotic normalization constants from elastic-scattering data

NUCLEAR REACTIONS ¹²C(α, α), E(cm)<10 MeV; analyzed p-wave and d-wave scattering phase shifts with simplified effective-range function; deduced asymptotic normalization constant (ANC) for -45 keV, 1- and -245 keV, 2+ bound states of ¹⁶O, lying below the ¹²C+α threshold.

Supersymmetric inversion of effective-range expansions

NUCLEAR REACTIONS ¹H, ¹n(p, p), E=350 MeV; analyzed scattering phase shifts from experimental data and compared with theoretical phase shifts from effective-range-function fits. Optimal inversion technique with parameterization of scattering phase shifts in terms of either scattering-matrix poles or effective-range Pade expansion.
