A method is introduced to determine a potential by inversion from both bound state energies and phase shifts, based upon the iterative perturbative [ital S] matrix to potential inversion procedure. The method is applied to determine the local potential reproducing low-energy [sup 3]He+[alpha] phase shifts as well as the [ital l]=1 bound states and lowest [ital l]=3 resonances in [sup 7]Be, for both the single channel RGM and empirical data. An even-parity potential is determined from phase shifts up to [ital l]=4, which differs significantly from the shape of the odd-parity term. The need for a pronounced parity-dependent potential underlying the RGM is confirmed, which strongly resembles that found in both [alpha]+[ital p] and [alpha]+[sup 12]C scattering.
