Double resonance via continuum states: Ionization quantum beats

Munir H. Nayfeh, Wallace Glab

Research output: Contribution to journalArticle


The two-photon process with continuum intermediate states is investigated. The line shape is found to be a singlet rather than a doublet as in the case of discrete intermediates (Autler-Townes doublet). The ionization line shape is a doublet and exhibits oscillations as a result of the coherence and the interference between the yields from the initial and final states.
