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.
