    "abstract": "We present the first observations of cylindrical symmetry breaking in highly\nexcited diamagnetic hydrogen with a small crossed electric field, and we give a\nsemiclassical interpretation of this effect. As the small perpendicular\nelectric field is added, the recurrence strengths of closed orbits decrease\nsmoothly to a minimum, and revive again. This phenomenon, caused by\ninterference among the electron waves that return to the nucleus, can be\ncomputed from the azimuthal dependence of the classical closed orbits.",
