Abstract
An attempt has been made to find realistic analytic wavefunctions suitable for use in (p,2p) reactions. The success of McCarthy and others using modified plane waves in inelastic scattering is exploited. In order to estimate the validity of the use of these wavefunctions we have looked at the elastic scattering of alpha particles from [88]Sr and [42]Ca in an approach similar to that of Dar (D1), although the Gell-Mann, Goldberger two potential formula is not used explicitly. The results obtained using these modified plane waves are compared to those obtained using the Optical Model. The limitations of the wavefunctions in this approach are discussed.
