Thomson cross section value
WebHere's a self-contained (hopefully clear) derivation. Step 1. Setup and definition of differential scattering cross-section. Let L denote the incident luminosity (number of incident particles per unit area, per unit time) of a beam to be scattered. We assume that we have a spherical detector at infinity with which to measure scattered particles ... WebThe Thomson cross-section may be used to yield an important limit on the luminosity of a self gravitating body, called the Eddington Limit. ... Problem 6.13 A minimum value for k is …
