A theoretical analysis of chaotic dynamics of the relativistic outer electron under the periodic perturbation due to the inner electron, based on Chirikov criterion, is given. The diffusion coefficient, the ionization rate and time are calculated.8 pages, latex, no figures, submitted to PRAChaotic DynamicsAtomic Physicstext
