摘要
The possibility is demonstrated of using exponential repulsive interaction potentials for the calculation of high-temperature integrals of collisions between atoms and molecules. An analytical formula is suggested, and the values of employed parameters are determined. The difference between the calculation results for complex interaction potentials with due regard for repulsion, potential well, and long-range attraction and the calculation results for the repulsive exponential interaction potential in the entire range of impact parameters is investigated. The dependence of the calculation accuracy on the choice of the region of approximation of the model potential by the exponential one is noted.
