Abstract
We consider the ionisation of atomic hydrogen by a strong infrared field. We extend and study in more depth an existing semi-analytical model. Starting from the time-dependent Schrödinger equation in momentum space and in the velocity gauge we substitute the kernel of the non-local Coulomb potential by a sum of N separable potentials, each of them supporting one hydrogen bound state. This leads to a set of N coupled one-dimensional linear Volterra integral equations to solve. We…

It is demonstrated that contributions from the direct tunneling processes in the absence of rescattering are not sufficient to describe the observed ATI spectra, and the high-energy portion of the spectrum, including recently discovered rings, are due to rescattering processes.
