Time-dependent convergent close coupling method for molecular ionization in laser fields

Abstract

We develop a time-dependent multi-configurational numerical technique for calculating ionization by short laser pulses of many-electron molecules. The method is based on the expansion of the wave function of a molecule into the eigenstates of the molecular ion. We classify this method as time-dependent convergent close coupling (TDCCC) because it uses the same symmetry for channel functions as the well-known convergent close coupling (CCC) method.
