THE REPULSIVE WALL OF THE AR-AR INTERATOMIC POTENTIAL REEXAMINED

The repulsive wall of the Ar-Ar interaction is reexamined with the purpose of rationalizing the apparent inconsistency between high energy beam results and high temperature transport data. A new piece-wise experimental potential is proposed which predicts not only the beam results but a large set of transport data up to 7000 K. Lower temperature/energy data are predicted almost equally as well as other state-of-the-art empirical potentials. © 1990 American Institute of Physics.
