Résumé
We investigate the efficient heating of quasi-free
electrons during the interaction of short infrared laser pulses with large
rare-gas clusters. In the framework of our mean-field classical transport
simulation we are able to explain the emission of characteristic x-rays at
moderate laser intensities (
Wcm - 2) where the
ponderomotive energy of the electrons is by far to low to allow for the
creation of inner-shell vacancies. We identify large-angle elastic
electron-ion scattering as an important heating mechanism at moderate laser
intensities.
