The oscillator strength of hydrogen lines
Abstract
A formal expression is given for the dependence of hydrogen-line oscillator strength on departure form LTE, and a method is proposed for determining this departure in the various sublevels of the hydrogen atom in solar prominences. Results for 10 solar prominences are given. Finally, the possible implications of a smaller population in the 2p level than in the 2s level are discussed.
