Angular Distributions for Double Ionization of Li{sup -} by an Ultrashort, Intense Laser Pulse
Journal Article

· Physical Review Letters
We predict photoelectron angular distributions for double ionization of Li{sup -} by both weak and intense ultrashort, linearly polarized laser pulses by direct numerical integration of the three-dimensional, time-dependent Schroedinger equation. Li{sup -} is treated as a two-active electron system. Near threshold, for low intensity we recover general features of angular distributions for one-photon double ionization. For the intense field (multiphoton) case, the photoelectron angular distribution changes significantly, particularly in directions parallel and perpendicular to the laser polarization axis.
