    Выдержка

    Eleven resonance functions are calculated in the exact trajectory model, which can be used for calculation of broadening coefficients γ of molecular lines during interactions with atoms of inert gases at very low temperatures. These functions correspond to the atom-atom potential and the potential V(R, θ) written in terms of Legendre polynomials. The functions are represented in analytical form. The broadening coefficients γ are calculated for absorption lines of CO perturbed by He and Ar at temperatures T from 300 to 2 K using the potential V(R, θ). It is shown that the dependence γ(T) for low temperatures T is determined by the potential well depth. For the CO–He system, a comparison with the experimental data is performed.
