"WebNote that the total cross-section (1329) is four times the geometric cross-section (i.e., the cross-section for classical particles bouncing off a hard sphere of radius ). However, low energy scattering implies relatively long wavelengths, so we would not expect to obtain the classical result in this limit. " - Total cross section
