Model of nuclear excitation by electronic motion in intense laser fields

摘要: A simple model of coupled electronic and collective nuclear motion is used to study energy-transfer processes in the presence intense short-wavelength laser fields. The complete Hamiltonian includes distinct nuclear, electronic, laser-field terms. semiclassical method extracting spectral information from generated trajectories calculate laser-electronic-nuclear rates. term describes a deformed heavy nucleus; it sufficiently treats motion, which lower frequency than that would be given by an individual-particle nucleon model. We specifically report on dynamics this model, energy transfers ensue, x-ray field, as function electron radial distance. This general problem basic interest studies laser-driven excitation.
