He-D 2 Total Scattering Cross Sections in the Velocity Range 760–2600 m/sec

Measurements of the total scattering cross section Q for He-D2 are reported over a range 760 m/sec≤ vr≤2600 m/sec in the relative speed. The data have been fit with a piecewise continuous potential that also gives a good fit to the diffusion coefficients, has the theoretical C6 coefficient, and join...

Description
Summary:Measurements of the total scattering cross section Q for He-D2 are reported over a range 760 m/sec≤ vr≤2600 m/sec in the relative speed. The data have been fit with a piecewise continuous potential that also gives a good fit to the diffusion coefficients, has the theoretical C6 coefficient, and joins smoothly with the short range a priori computed potential.
