摘要：

The interaction of a weakly bound Rydberg electron with an electromagnetic half-cycle pulse (HCP) is described with the help of a multidimensional semiclassical treatment. This approach relates the quantum evolution of the electron to its underlying classical dynamics. The method is nonperturbative, and is valid for arbitrary spatial and temporal shapes of the applied HCP. On the basis of this approach, angle- and energy-resolved spectra resulting from the ionization of Rydberg atoms by HCP's are analyzed. The different types of spectra obtainable in the sudden-impact approximation are characterized in terms of the appearing semiclassical scattering phenomena. Typical modifications of the spectra originating from finite-pulse effect are discussed. [S1050-2947(99)03108-X].
