The calculation of excitation cross-sections of collisions between Ne isotope atoms with HF molecule

Abstract

In this paper, we use the Huxley potential function to fit the interaction energy data, which have been calculated at the theoretical level of the QCISD(T)/aug-cc-pVTZ. Differential and partial cross-sections of 16Ne, 20Ne, 34Ne atoms and HF molecule collisions are calculated by the accurate close-coupling approximation method when the incident energy is 100meV. We study the changing tendencies of Ne-HF collisional cross-sections with Ne isotopic substitution.
