Comments on the existence of low-energy d-wave resonances in electron-fluorine atom scattering

It is argued that the very narrow, low-energy 1D/sup o/ and 1P/sup o/ d-wave shape resonances in the e--F system reported by Ormonde must be artifacts. Evidence that this is so is drawn from numerical Hartree-Fock calculations, from construction of effective local potentials, from calculations with model polarization potentials, and from extensive configuration-interaction/stabilization computations. No evidence of such resonance behavior is found in any of these calculations
