Stark-induced resonances in the photoionization of hydrogen

Research output: Contribution to journalArticlepeer-review


We report the first observation of electric-field-induced resonances in the multistep photoionization of hydrogen. Asymmetric profiles having blue wings are observed near the photoionization limit resulting from tunneling across the Stark-Coulomb combined potential (shape resonance). We measured the dependence of the spacing of the resonances on the electric field strength.
