Abstract
Quantum-mechanical calculations of multiphoton double ionization by intense laser pulses show that the total-kinetic-energy spectrum of the photoelect rons consists of peaks separated by the photon energy, analogous to ordinar y above-threshold ionization. Related structures appear in the two-electron and in the recoil-ion momentum distribution. We propose a method to extrac t the total-kinetic-energy spectrum from the experimental recoil-ion spectr um.
