Abstract: There is a very general analytical mathematical problem concerning Rutherford scattering and the collision of electrons with ions in presence of a strong periodical electric field (as in a strong laser field.) It is shown that the structure of the phase space of the problem depends only on one parameter. When this parameter is less the unity (and that is when the laser field is strong), stochastical dynamics will dominate. The numerical and analytical description of the problem will be presented. This result has significant consequences for several experimental areas, (Joule heating of plasmas, hot electron production, the generation of higher harmonics…) and they will be discussed.
