Scattering of High Velocity Neutral Particles. V. Neon-Neon

Total collision cross sections have been measured for neon atoms with energies between 500 and 2100 ev scattered in room temperature neon. The experimental results have been treated to obtain potential energy information for the interaction of two neon atoms. The analytical relation, which may be represented by V(r)=5.00×10−10/r9.99ergfor r between 1.76 A and 2.13 A, is consistent with the potential, valid at larger separation distances, which has been derived from measurements of gaseous compressibility, viscosity, and crystal properties.
