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:

The intermolecular pair-potential energy functions of the inert gases
TL;DR: The pair potential energy functions of the inert gas molecules may now be defined with some accuracy as a result of recent advances as discussed by the authors, such as the determination of bulk properties with greater accuracy and over wider ranges of temperature, particularly where this has revealed large errors in the existing well-established data.

Experimental total collision cross sections in the glory region for noble gas systems
TL;DR: In this article, a cross-supersonic beam apparatus measurements have been performed on the total cross section as a function of velocity in the thermal range for scattering of Ne, Ar, Kr and Xe by Ne, Kr, Xe, and Ar.

Atomic and chemical effects in Sm and Sm2O3 photoelectron spectra
TL;DR: In this paper, a comparative study of Sm and Sm2O3 photoelectron spectra is presented, showing that they are well interpreted by atomic effects, except for the Sm 2O3 d spectra which exhibit chemical effects.

The Simons-Parr-Finlan modified Dunham expansion: a generalized potential model for the analysis of differential elastic molecular beam scattering cross sections
R.W. Bickes,R.B. Bernstein +1 more
TL;DR: The Simons-Parr-Finlan (SPF) modification of the Dunham expansion as mentioned in this paper offers a unified and compact representation of all realistic, multiparameter potential models employed for interpreting angular distribution of elastic molecular beam scattering at thermal energies.

Classical Trajectory Study of Energy Transfer in Collisions of Highly Excited Allyl Radical with Argon
TL;DR: A study of energy transfer in single collisions of highly vibrationally excited allyl radical in argon and the sensitivity of results to the interaction potential is considered and the potential is shown to be suitable for future applications involving different isomers of the allyl.

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.
