Symétrisation des voies d'entrée et de sortie en théorie des collisions complexes

Abstract

We show that the choice of a common basis for entrance and exit channels eliminates the post-prior discrepancy which appears when the Born approximation is applied to transition matrix elements of rearrangement collisions. The solution of the three-body Schrödinger equation gives the eigenvectors of that common basis in (d, p) reactions. The transition matrix element is then obtained by integrating the product of Fourier transformed initial states, final states, and the potentials. The integration is performed over a Fourier space bearing a special metric.
