Abstract
We extend a recently developed three-dimensional semiclassical model to study double and triple ionization of Ne driven by infrared laser pulses at various intensities. This model fully accounts for the Coulomb singularity of each electron with the core, as well as for the interaction of a recolliding electron with a bound electron. The model avoids artificial autoionization by employing effective Coulomb potentials to describe the interaction between bound electrons. Using the extended effective-Coulomb-potential for bound-bound electrons (ECBB) model, we compute triple and double ionization spectra. For instance, we compute the distributions of the sum of the final momenta along the laser field of the escaping electrons. Taking focal volume averaging into account, we find very good agreement with experimental results, particularly for triple ionization. Also, we identify the main pathways of triple and double ionization and explain how these pathways give rise to the main features of the triple and double ionization spectra.
