The Born Oppenheimer wave function near level crossing
J. E. Avron, A. Gordon
The standard Born Oppenheimer theory does not give an accurate description of the wave function near points of level crossing. We give such a description near an isotropic conic cr…

Born-Oppenheimer Approximation near Level Crossing
A. Gordon, J. E. Avron
We consider the Born-Oppenheimer problem near conical intersection in two dimensions. For energies close to the crossing energy we describe the wave function near an isotropic cros…
