Analytic distorted waves for intermediate-energy alpha particles

It is shown that physically consistent and realistic values of all the parameters can be found for a model that represents the distorted waves in the distorted-wave Born approximation for collective α inelastic scattering by a properly normalized decaying plane wave. The significance of this achievement in a thoroughly understood reaction is that we are now able to obtain analytic distorted waves that are sufficiently realistic and sufficiently simple to use in off-shell distorted-wave impulse approximation calculations of reactions of current interest requiring microscopic descriptions of the reaction mechanism.NUCLEAR REACTIONS ⁶²Ni(α,α^'), $E=33, 50, 100$ MeV; ²⁴Mg, ⁴⁸Ti(α,α^'), $E=41$ MeV; ³²S, ⁸⁸Sr(α,α^'), $E=42$ MeV; analytic DWBA, calculated σ(θ).
