Abstract
In this present work we study deuteron stripping reactions from a microscopic point of view. We define an open channel wavefunction which has the same asymptotic behaviour as the total wavefunction describing the total system (target plus incident deuteron) by simply extending the asymptotic form of the respective open channel wavefunctions to all space. We work with explicitly antisymmetrized wavefunctions so that the Pauli principle is always taken into account. By means of the Unified Theory of Reactions we obtain a system of coupled Schrödinger equations for the elastic deuteron scattering and the inelastic proton stripping amplitudes, after having analyzed carefully the respective projection operators. We obtain effective stripping potentials. We estimate the relative importance of corrections to the usual coupling potentials, which arise due to antisymmetry and nonorthogonality of the channel wavefunctions, by means of a DWBA. The effect of nonorthogonality becomes important when the channel wavefunctions are antisymmetrized.
