Description
The potential energy V is placed into the unperturbed Hamiltonian H0 and the kinetic energy K remains in the perturbation H1. It is shown that a convergent N/D method, through standard Fredholm determinants, provides suitable matrix elements of an operator such as H1 + H1(E - H)-1H1. This con-firms that the kinetic energy can be used as a perturbation in the Brillouin-Wigner theory. (author)
