An approximate numerical method of solving collision integrals for the Morse potential in a wide parameter interval
Annotation
The calculation technique for the collision integrals with model potentials has been refined. The collision integrals were calculated for the Morse potential in wide ranges of the reduced temperature and the parameter $\beta$. The applicability limits of the calculation of the collision integrals for the Morse potential at small $\beta$ values have been found. The calculated values of the collision integrals have been fitted with analytical functions. The obtained results were compared critically with the published data. The temperature derivatives of the collision integrals have been analyzed.
