Abstract
Results of numerical and theoretical investigations of electron–ion collision processes in plasma in a strong laser field are represented. It is shown both numerically and analytically that the existing knowledge about e–i collisions in a rather strong field should be revised. Moreover, it was found that in such fields, along with the efficient growth of effective cross section, the effective bunching of electrons at phases takes place simultaneously. Effects are observed both at the linear and the circular laser field polarization. The quasiphenomenological approach for the electron–ion collision integral derivation for the case of strong fields is suggested.
