摘要：
Electron energy absorption in laser irradiated plasma is determined by sum of rates of multiphoton induced absorption and emission. These rates contain squares of the Bessel functions. It was shown that in moderate laser field terms with absorption and emission of several photons are large, but cancel exactly each to other. Therefore we should take into account terms with absorption and emission of only one laser photon (first order perturbation theory). ((c) 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
