Research ArticleOpen accessIn the author namesA Priori Estimation of the Resolvent on Approximation of Born-OppenheimerSabria Bouheroum-Mentri, Amina BenbernouIn this study, we estimate the resolvent of the two bodies Shrodinger operator perturbed by a potential of Coulombian type on Hilbert space when h tends to zero. Using the Feschbach method, we first distorted it and then reduced it to a diagonal matrix. We considered a case where two energy levels cross in the classical forbidden region. Under the … …Journal of Mathematics and Statistics, Vol. 3, Issue 2 · 30 Jun 2007 · 6,725 accessesView PDFCite
