A simple self-consistent model for the generation of fast electrons during the interaction between two opposite beams of ultrashort and ultraintense laser pulse and their middle foil target is proposed. The derivation of the theory shows that the electrons in an electron cloud adjacent to the target surface will be strongly accelerated and will be fast electrons because of their resonant interactions with the oscillating components of the ponderomotive force of the laser light.
