When the Rydberg atom prepared in an n<sub>0</sub>s state (n<sub>0</sub>≫1) is exposed to a sufficiently intense laser pulse of a duration not exceedingly short compared with the initial-state Kepler period, the resulting photoelectron angular distributions are not only governed by the <i>p</i> partial wave but are shown to be shaped by higher-order waves as well, provided that the frequency assumed permits the higher-angular-momentum Rydberg states about the initial n<sub>0</sub>s state to be involved in the process owing to multiple resonant Raman transitions.
