Photoionization of the hydrogen atom near the ionization limit in strong electric fields

· Phys. Rev. A; (United States)
The Stark spectroscopy of the hydrogen atom has been investigated near the ionization threshold in static homogeneous external electric fields from approx.1000 to approx.8000 V/cm with use of a two-step excitation H(n = 1)+h /sub vuv/ H(n = 2)+h /sub uv/ H( with vuv and uv laser radiation, independently tunable and linearly polarized either parallel ( ) or perpendicular (sigma) with respect to the external field. Different from other, nonhydrogenic atoms, the hydrogen atom is a peculiar case insofar as the initial states of H(n = 2), from which excitation takes place, are essentially of parabolic character at the field strengths employed in this study.
