    "abstract": "Phase shifts for $\\alpha$ + nucleon scattering generated by a multichannel\nRGM model of the five-nucleon system are subjected to iterative-perturbative\n``mixed-case\" inversion for energies below the reaction threshold. The\nresulting phase-equivalent potentials are compared with local potentials\ncalculated from the inversion of empirical phase shifts. A strong similarity is\nrevealed between the two sets of potentials, most notably in the description by\na parity- and energy-dependent local potential. In particular, the RGM-derived\nand empirical potentials share a distinctive form of parity dependence in which\nthe odd-parity component is of greater radial extent. Comparison with\npotentials representing single-channel RGM phase shifts exhibits the importance\nof the coupled channels in terms of local potentials. The relative wave\nfunctions derived from RGM are very different to those for the phase-equivalent\nlocal potentials.",
