Image of FIG. 1.
FIG. 1.

Electron energy spectra obtained from the quantum and classical models for the following set of parameters: , , , . (a) Spectrum obtained with the ADI method for (solid line) and (dotted line); (b) the same spectrum obtained with the spectral method for (solid line) and (dotted line). The thick dashed (thin dash-dotted) line in panel (b) shows the result of the classical dynamical model for . The dashed line in panel (a) shows the result of the classical model of instantaneous collisions. Also shown for comparison is the energy spectrum of the electron in the ground state of hydrogen (dotted-dashed line).
