The Green's function method for implicitly evaluating the sums over intermediate states occurring in the study of multiphoton processes is revisited. Partieular emphasis is given to bound-bound transitions and to the numerical techniques used to implement the method. This is also extended to the important case in which the sum over intermediate states must be performed with respect to an incomplete set. The accuracy of the method is tested against very precise results on atomic hydrogen obtained by direct summation over intermediate states.

Abstract
The Green's function method for implicitly evaluating the sums over intermediate states occurring in the study of multiphoton processes is revisited. Partieular emphasis is given to bound-bound transitions and to the numerical techniques used to implement the method. This is also extended to the important case in which the sum over intermediate states must be performed with respect to an incomplete set. The accuracy of the method is tested against very precise results on atomic hydrogen obtained by direct summation over intermediate states.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
