Abstract
The time-dependent, single-particle Schrödinger equation with a finite-range potential is solved numerically on a three-dimensional
spherical domain. In order to correctly account for outgoing waves, perfect reflection-free radiation boundary conditions
are used on the surface of a sphere. These are computationally most effective if the particle wavefunction is expanded in
the set of spherical harmonics and computations are performed in the Kramers-Henneberger accelerated frame. The method allows
one to solve the full ionization dynamics in intense laser fields within a small region of atomic dimensions.
