A nonlinear dependence of the Lamb-dip width at CO2 transitions on pressure caused by scattering at small angles under collisions has experimentally been found. The analysis of the results allowed us to determine some characteristic parameters of elastic scattering under collisions, such as the total scattering cross-section and the characteristic elastic scattering angle, which proved to be equal to 480 A2 and 10-2 rad, respectively.
