Change of Integration Variables in Calculations of the Coefficients of Broadening and Shift of Spectral Lines of Molecules by the Robert-Bonamy Method

摘要

The transformation of the integration domain upon passage from the variables impact distance-initial relative velocity to the variables closest approach distance-initial relative velocity in the Robert-Bonamy method for an arbitrary isotropic potential is considered. As an example, the result obtained is applied to the Lennard-Jones potential.
