    "abstract": "The dynamics of Rydberg states of a hydrogen atom subject simultaneously to\nuniform static electric field and two microwave fields with commensurate\nfrequencies is considered in the range of small fields amplitudes. In the\ncertain range of the parameters of the system the classical secular motion of\nthe electronic ellipse reveals chaotic behavior. Quantum mechanically, when the\nfine structure of the atom is taken into account, the energy level statistics\nobey predictions appropriate for the symplectic Gaussian random matrix\nensemble.",
