Stark Effect for the Rydberg States of Hydrogen Atom.

摘要

The Stark shifts and widths for highly excited states, n=15-30, of hydrogen atom in strong electric field E are calculated (the E values exceed the classical ionization threshold E of the atom). The calculation method is summation of divergent perturbation series (PS) by means of Hermite-Pade approximants (HPA). The 1/n-expansion is also briefly discussed. The results of the calculation agree with the experimental data. 16 refs.; 5 figs. (Atomindex citation 19:069726)
