Experimental study of short-duration intermolecular forces in hydrogen
Abstract
The paper describes an attempt at an empirical determination of the parameters of a potential-energy surface model for H2-H2 collisions. Data for computing the potential-energy surface were acquired through minicomputer-controlled measurements of differential scattering of an H2 beam (with an energy of 600 eV) in an H2 atmosphere at scattering angles varying in the range 0-27 mrad. An additive potential surface and an average potential have been determined, which agree well with experimental data and can be used to compute the macroscopic properties of hydrogen in gaseous and solid phases.
