Determination of dispersion energy coefficients for SF6–SF6 and SF6–Ne at low energies from experiments with supersonic pulsed jets

Abstract

A method for the experimental determination of constant C6 for the attractive branch of interaction potential was based on the kinetic model of a supersonic pulsed jet expansion, was suggested. The measured quantity is a position of maximum on the time-of-flight spectrum connected with C6 and source conditions by analytical relationship according to the model. The values of C6 thus determined for SF6–SF6 and SF6–Ne agree satisfactorily with the values obtained from the experiments with supersonic steady jets.
Key words: dispersion coefficient C6, supersonic pulsed jet, time-of-flight spectrum.
