Equivalent local potentials for nucleon-alpha scattering

Quantum mechanical inversion is used to obtain l-independent phase equivalent local potentials to microscopic nucleon-alpha potentials of Lassaut and Vinh Mau between $E_{\mathrm{lab}=15\mathrm{}}$ and 25 MeV. These potentials are compared with the corresponding local potentials obtained in the Perey-Saxon approximation.
