A microscopic theory of a quasi-crystalline transition layer on the surface of semi-infinite liquid dielectrics upon brewster light reflection and the near-field effect

Effect of argon buffer gas and the dimer component on the optical properties of sodium vapor

“…Let us make use of the coupled dipole method, which we have repeatedly used previously to study nanosized objects and structures and which has shown good agreement with both experimental data and ab initio exact numerical calculations [9][10][11]. Within this approach, the field at an arbitrary point in the medium is written in the form [12,13]:…”

“…In this paper, we consider the interaction between the sodium dimers and the electromagnetic field within the semiclassical approach proposed and tested earlier in [13][14][15]. Let us write the field created by the dimer at any point in space according to (1) in the form:…”

“…The major difficulty in using formulas (6), (13) to calculate the polarizability of the atoms and the refractive index of argon is the need to calculate the decay constant γ Ar , which in a multicomponent system depends in a very complicated way on its parameters. We determine the value of this physical quantity from the experimental curve under consideration, ignoring specific line broadening mechanisms.…”
