This graph image could be, re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, "please upload it." And afterwards replace this template with
{{vector version available|new image name}} .
It is recommended——to name the——SVG file “Xsection2.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
Summary
DescriptionXsection2.png | 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. |
