Starting from an exact three-body theory for the nuclear rearrangement reaction a+(b+c)→b+(a+c), we study a generalized distorted-wave approximation in the momentum-space representation. Using suitable kinematic transformations we recast this representation in a form coinciding with the one obtained by means of the Feynman diagram summation method.

Abstract
Starting from an exact three-body theory for the nuclear rearrangement reaction a+(b+c)→b+(a+c), we study a generalized distorted-wave approximation in the momentum-space representation. Using suitable kinematic transformations we recast this representation in a form coinciding with the one obtained by means of the Feynman diagram summation method. The generalized potential responsible for the transition will be written in a compact form involving the resolvent operator for the a-b subsystem.
