Abstract
An analysis of an approximate expression for the optical potential given by its functional derivative formulation, shows which are the diagrams left out at each order. A possible method which attempts to introduce the missing diagrams without losing the advantages provided by the functional derivative approach, is proposed. Numerical results are reported for LiH and H2O.File in questo prodotto:
