Query: Chaotization of the Supercritical Atom   Chaotization of supercritical (Z>137) hydrogenlike atom in the monochromatic
field is investigated. A theoretical analysis of chaotic dynamics of the
relativistic electron based on Chirikov criterion is given. Critical value of
the external field at which chaotization will occur is evaluated analytically.
The diffusion coefficient is also calculated.
