Sections efficaces totales d'une molécule diatomique dans l'approximation de Born-Oppenheimer

Abstract : In this work, we consider the Born-Oppenheimer approximation for diatomic molecules (i.e. when the mass ratio electronic mass/ nucleic mass tends to 0). To this end, we introduce an adiabatic approximation that includes several electronic levels. We assume that the later do not cross. In this framework, we prove a semiclassical resolvent estimate and deduce from it the semiclassical asymptotics of total cross-sections.
