In this paper we suggest that theories treating two interacting objects in a different manner (for instance electromagnetic field of a laser classically, and the interacting atom as a quantum object) should be called “mixed”. Mixed theories are n

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 th

Here, the method of including nonzero initial momenta for ejected electrons in strong infrared laser fields is further developed [8]. It has been shown that, apart from being natural, including the nonzero initial momenta enables one to go into a dee

Tunneling regime, introduced by Keldysh, in the interaction of strong lasers with atoms has been now accepted as the reliable method for describing processes when low frequency lasers are involved. Yet it was always assumed that the ionized electrons

In the case of the short-range potential [1,5,8,9], the estimation of the probability of ionization of atoms is carried along taking into account the approximation (Keldysh approximation) which states that this kind of potential does not affect the e

Potassium atoms in circularly polarized laser field whose intensity (I) varies from 2 × 10 W/cm to 2.5 × 10 W/cm were studied. In the case when there is zero initial momentum, transition rate (that depends only on I) exhibits standard behaviour: as

Here are shown two different transition rates, one obtained in the ADK-theory [1,2] and the other one for ADK result with turning point corrected with the Coulomb interaction – let us denote it cADK [1,3], in both cases the changing of charge state

Estimation of transition rate of ionization of atoms for short range potential, based on assumptions of Keldysh approximation, shows that short-range potential does not affect the energy of the final state of ejected electron, when it leaves the atom

We have shown that Noether's theorem [16] has a corollary which proves non-conservation of angular momentum and spin in ``mixed'' theories (the ones that combine classical and quantum approach). As laser field is treated classically and atoms with wh

The two formulae for the energy at which the maximum number of ejected photoelectrons are detected are examined in this paper; one formula is Emax with non-zero momentum included in both the exponent and the pre-exponent part of the expression, and t
