A simplified representation of intermolecular potential energy
Geoffrey C. Maitland,E.B. Smith +1 more
TLDR
In this article, a new simple function which is capable of representing the intermolecular pair potential energy of the inert gases is proposed, based on the traditional n -6 reciprocal power potential with the modification that n is regarded as a function of separation rather than as a constant.About:

On the direct inversion of total scattering cross sections beyond the glory region
TL;DR: In this paper, it is shown that the average cross section can be accurately retrieved from the data, without the assumption of a mathematical model for the potential, and that the retrieved values can be directly inverted to numerical values of the potential tail.

Thermophysical Properties of Gaseous Tungsten Hexafluoride From Speed-of-Sound Measurements
TL;DR: In this article, the authors measured the speed of sound in gaseous WF6 using a highly precise acoustic resonance technique and fitted the speed-of-sound data to virial equations of state to obtain the temperature dependent density virial coefficients.

Improved Error Bounds for the Long-Range Forces between Atoms
George Starkschall,Roy G. Gordon +1 more
TL;DR: In this paper, error bounds for the long-range attractive potential between pairs of atoms and molecules have been calculated by constructing oscillator strength distributions which reproduce known dynamic polarizabilities, oscillator strengths, and photoionization cross sections.
