    "abstract": "In the combination of crossed electric and magnetic fields and the Coulomb\nfield of the atomic nucleus the spectrum of the Rydberg electron in the\nvicinity of the Stark saddle-point are investigated at a quantum mechanical\nlevel. The results expose a quantum anomaly dissociation: quasibound states\nnear and above the saddle-point ionization limit predicted at the\nsemi-classical level disappear at a quantum mechanical level.",
