    "abstract": "We consider the Born-Oppenheimer problem near conical intersection in two\ndimensions. For energies close to the crossing energy we describe the wave\nfunction near an isotropic crossing and show that it is related to generalized\nhypergeometric functions 0F3. This function is to a conical intersection what\nthe Airy function is to a classical turning point. As an application we\ncalculate the anomalous Zeeman shift of vibrational levels near a crossing.",
