Photoionization of H2 using the molecular R-matrix with time approach

Abstract

We present results of the rst calculations using the variational ab initio molecular R-matrix with time approach. We have calculated two and four-photon ionization cross sections for H2 and studied the eects of electron correlation and choice of the Gaussian atomic basis sets.

Our results are compared with earlier calculations.
