During the process of adjusting the ADK-theory for the superstrong laser fields we took some part in few past years [1, 7, 8], mainly in analyzing the consequences of the influence of atom charge Z, being changed during the ionization of atoms, on the transition rate of ejected electrons. In this activity we introduced a slightly changed variant of ADK-theory [3], which we began to call corrected ADK-theory, cADK, for short [8]. Now, cADK-theory is not experimentally challenged yet, but it’s results are in accordance with many predictions [see, for instance 1, 7–9]. In present work, we used calculations of modified ionization potential of atom E i , in order to improve formula for transition rate W cADK . As we already discussed the transition rate dependence on the atom charges state Z [1], now we explained better the differences of the two variants of the theory, ADK and cADK. Of course, our predictions need experimental check.
