Title: New effect in Stark spectroscopy of atomic hydrogen: dynamic resonance

Abstract

We investigate analytically the spectrum of the hydrogen atom in an electric field E(t) = E/sub 0/ cos ..omega..t+F, where FperpendicularE/sub 0/. In the case when the splitting in the time-averaged field < E(t) > coincides with (2--1) ..omega.., where perpendicular = 1, 2, 3..., an effect called dynamic resonance is produced. The resonance occurs between the quasienergy states and is multiparticle and multiphoton. The hydrogen spectral lines undergo additional splitting under these conditions. The theory of dynamic resonance provides a physical explanation of the results of the numerical calculation of the L/sub ..cap alpha../ spectrum in crossed electric fields E/sub 0/ cos ..omega..t and F, as reported by Cohn, Bakshi, and Kalman (Phys. Rev. Lett. 29, 324 (1974)). We show also that fields with fixed phases and fields with random phases can exert different resonant action on the hydrogen spectral lines that start from levels with n> or =3. The dynamic resonance effect can be experimentally observed ad used both in laser physics and in plasma physics (in particular, to detect Langmuir solitons).
