Resumen:
We analyze the two-dimensional angular momentum-energy distribution ofelectrons emitted from argon by short laser pulses. We identify characteristic features of both multiphoton and tunneling ionization in the partial-wave distribution for Keldysh parameters close to unity. We observe a remarkable degree of quantum-classical correspondence in the photoinization process which becomes even more pronounced after intensity averaging over the focal volume. We derive an energy-dependent cut-o for the highest angular momentum accessible within the framework of the strong-eld approximation, which accurately reproduces the partial wave distributions found from solutions of the time-dependent Schrodinger equation.
