THE EXTENDED LAW OF CORRESPONDING - STATES AND THE INTERMOLECULAR POTENTIALS FOR Ar-Ar, Ar-Kr AND Kr-Kr

Abstract
An inversion procedure is used to obtain from the extended principle of
corresponding - states the pair interaction potentials for argon, krypton and its
mixture over a tetnperature range from absolute zero to the onset of ionization.
The experimentally-reduced viscosity collision integrals obtained from the
corresponding - states correlation have been inverted directly to give the
reduced-intermolecular potential energy curves corresponding to the collision
integrals. These directly determined potentials are in good agreement with the
potentials independently obtained from the molecular-beam scattering
measurements, which were fitted by ESMSV for Ar-Ar and Kr-Kr and by
SMSV for Ar-Kr
