Best Fit

Differential collision cross sections for H2–noble gas pairs have been measured and analyzed via a best fit procedure. The data are well described by Lennard–Jones (12,6) (LJ) and Buckingham–Corner (BC) potentials and yield model independent values for σ, the location of the zero of the potential. For H2–Ne, H2–Ar, and H2–Kr, σ values are respectively 2.85, 3.07, and 3.21 Å, with uncertainties [Formula: see text].

Beam Technique

The angular distribution of Ar + Ar scattering at E = 9.16 × 10−14 erg was measured out to the rainbow pattern (supernumerary rainbow and part of the rainbow peak) by the crossed molecular beam technique, with mass spectrometric detection. This distribution was compared to calculated differential cross sections. Total cross sections, and spectroscopic constants for Ar2 were also calculated. The trial potentials were L.J.-12,6, LJ.-20,6, a modified Lennard–Jones potential (L.J.-14,12,8,6) and the Bobetic–Barker potential. The Bobetic–Barker potential is the one most consistent with cross section and spectroscopic experiments.
