An analytic study is made of the spectrum of a hydrogen atom in an electric field of the form E(t) = E/sub D/(t)+F, where the one-dimensional field E/sub D/(t) = E/sub 0/ cos (..omega..t+phi) can be the field of regular plasma oscillations (e.g., Langmuir oscillations) or the field of coherent electromagnetic radiation which is interacting with the plasma, while F is a quasistatic field which results from low-frequency electrostatic oscillations of the plasma and/or ion microfields. No restriction is placed on the relative orientation of the vectors E/sub D/(t) and F. When the splitting of the upper or lower atomic level in the time-averaged field is equal to q..omega.. (q = 1, 2, 3,...), a resonance effect occurs and gives rise to an additional splitting of the spectral line. The frequencies of this resonant additional splitting are found for an arbitrary spectral line of hydrogen. Structural features due to the q-quantum resonance on the resultant profile of the spectral line (the profile averaged over the distribution of the fields F) are analyzed. Methodological recommendations are offered regarding the use of these structural features to measure the parameters of the fields E/sub D/(t) in plasmas.
