THERMAL PHOTOIONIZATION OF THE RYDBERG ATOMS BY THE BLACKBODY RADIATION: NEW RELATIVISTIC APPROACH

Within the gauge-invariant quantum electrodynamics perturbation theory it is presented a new relativistic approach to definition of the thermal photoionization characteristics for the Rydberg atoms, in particular, the Rydberg atoms, ionized by the Blackbody radiation. Theory of corresponding phenomena in the Rydberg systems is a basis for creation of new class of the atomic sensors.
