On the Electric Field Effect on the Dynamics of High Rydberg States of Hydrogen Atom and the Model of ZEKE Spectroscopy

Abstract

AbstractIn this paper, the studies of the dynamics of the high Rydberg states for n = 10 and n = 100 of hydrogen atom under the influence of an electric field will be reported. It will be shown from our calculated results that the two time constants of τslow ≈︁ 1 – 10 μs and τfast ≈︁ 1 – 10 ns obseved in ZEKE experiments are obtained in the stray field condition, i.e., F = 10 – 100 mV/cm. To treat the ZEKE states of complex systems like many‐electron atoms, molecules, clusters etc., the inverse Born‐Oppenheimer approximation can be used and it will be discussed.
