Inelastic Scattering of Broadband Electron Wave Packets Driven by an Intense Midinfrared Laser Field
Abstract
Intense, 100 fs laser pulses at 3.2 and 3.6μm are used to generate, by multiphoton ionization, broadband wave packets with up to 400 eV of kinetic energy and charge states up to Xe+6. The multiple ionization pathways are well described by a white electron wave packet and field-free inelastic cross sections, averaged over the intensity-dependent energy distribution for (e, ne) electron impact ionization. The analysis also suggests a contribution from a 4d core excitation, or giant resonance, in xenon.
