[edit] Summary
| Description |
This figure plots equivalent quantities used in the theory of scattering from composite specimens, but with a variety of units, onto a single plot. The grey dots are for inelastic scattering of a 300 keV electron passing through a specimen of solid Silicon, as well as for an electron near its most strongly interacting energy of around 70 eV in a metal. The gold dot shows how a 300 keV electron has a shorter distance mean free path but about the same area cross-section. The mean free path between collisions of nitrogen molecules in air at STP is shown by the darker blue-green dot, while the cyan dot shows approximately where the mean free path for light scattering by fog might plot. The black and yellow dots denote nuclear cross-sections, e.g. in the latter case for Rutherford backscattering of a He nucleus from a gold foil. |
