Abstract
Quantum-mechanical calculations of multiphoton double ionization by intense laser pulses show that the total-kinetic-energy spectrum of the photoelectrons consists of peaks separated by the photon energy, analogous to ordinary above-threshold ionization. Related structures appear in the two-electron and in the recoil-ion momentum distribution. We propose a method to extract the total-kinetic-energy spectrum from the experimental recoil-ion spectrum.Keywords
