Test of the Quantum Chaoticity Criterion for Diamagnetic Kepler Problem
  The earlier suggested criterion of quantum chaoticity, borrowed from the nuclear compound resonance theory, is used in the analysis of the quantum diamagnetic Kepler problem (the spinless charged particle motion in the Coulomb and homogenious magnetic fields).
