Besides the usual Wigner-Kirkwood expansion, oscillatory terms are derived. In the case of a Woods-Saxon potential, a smallness parameter is defined, which determines the convergence of the series and explains the very rapid convergence of the Wigner-Kirkwood expansion for average (nuclear) binding energies.10 p.application/pdfeng(c) The American Physical Society, 1987Teoria quànticaAnàlisi numèricaNumerical analysisQuantum theoryinfo:eu-repo/semantics/article35055info:eu-repo/semantics/openAccess
