Abstract: We consider the motion of atoms in a cell free of a buffer gas with an antirelaxation wall coating on the spectrum and shift of the coherent population trapping resonance. We compare two types of reflection of atoms, viz., elastic (specular) and diffuse reflection, when the velocity of an atom after its reflection is determined by the wall temperature, as well by the quality of the antirelaxation wall coating. It is shown that for both types of reflection, a nonmonotonic dependence of the coherent population trapping resonance shift on the cell size is observed. In the case of diffuse reflection, the shift can change sign, and a complex two-hump structure of the coherent population trapping resonance is observed in a certain range of cell lengths. The dependence of the detected effects on the laser radiation spectral width is analyzed. [ABSTRACT FROM AUTHOR]
