摘要

The reflection of resonant optical radiation from the boundary of a gaseous medium has long been considered a trivial illustration of the laws of physical optics [1]. The use of this effect for studying the interactions of atoms with one another and with the solid surface became possible only after the experimental discovery [2] and theoretical interpretation [2, 3] of narrow resonances in reflection spectra, free of Doppler broadening. First of all, the resonant collisional broadening in the centers of atomic lines, inaccessible to the standard absorption spectroscopy because of self-absorption effects in optically dense atomic vapors, was determined [4]. The constants of the Van der Waals interaction between a solid surface and a resonantly excited atom, for which other measurement techniques are not known, were also measured [5]. At the same time, inadequacies of the theoretical treatment gave rise to certain problems and paradoxes with interpreting experimental data without proper account for such attendant circumstances as the nonexponential absorption in the medium, deviation of the local field from the mean various factors causing shifts, broadening, and deformation in the spectral contours of the lines of selective mirror reflection.
