摘要
In standard quasiclassical trajectory calculations, each trajectory has the same statistical weight. Alternately, the Gaussian weighting method is an ad hoc procedure which consists in weighting each trajectory by a Gaussian-like coefficient such that the closer the final actions to integer values, the larger the coefficient. The goal of the present note is to justify such a method in the framework of classical S matrix theory. (C) 2004 Elsevier B.V. All rights reserved.
