Description
In [1] the planar channeling and quasicharacteristic radiation (QCR) in charged planes (111) of ionic crystals LiH, LiD and LiF were studied. In the report the potentials of electron interaction with charged planes (111) and charged axes [110] of LiF crystal, as well as in other crystals of lithium halides (LiCl, LiBr and LiI) are calculated by methodic [2]. It is shown that the contribution of the Coulomb component into the structure of potential wells both in planar and axial cases is very essential. It is shown also that potential wells in Li+–planes of and crystals don’t disappear up to the melting temperature. From the other hand in and crystals these wells are inverted into potential barriers at T=600K and T=450K respectively. The similar effects take place at axial channeling.
On the basis of the numerical solution of Schrödinger equation the energy levels and wave functions for the relativistic electrons channeling along (111) planes and along [110] axis are found. In a dipole approximation the spectra of QCR are calculated for various regimes of channeling.
