Аннотация:The investigation of resonance ionization by electron impact from laser excited and aligned atoms is extended to the domain of intermediate energies of the incident electrons. Calculations are performed in the distorted-wave approximation for the total excitation cross sections and anisotropy of the ejected electrons for the doublet of autoionizing resonances 2p(5)3s3p(2)D(3/2,5/2) in sodium. Predictions are made for a new experiment mode with a fixed position of the electron detector and a rotating polarization of the laser beam and for the (e,2e) angular correlation functions.
