Is collsional frequency actually frequency per an electron?

[QUOTE="sunrah, post: 5497041, member: 365167"] It is just the frequency of collisions bbetween incident and target particles. The mean free path can be defined as l = 1/(σ*n[SUB]t[/SUB]). You can think of this as the average distance traveled between collisions. So your equation can be rewritten as nu = v/l = speed/distance. This is obviously in units of Hz, e.g. it is a frequency. Perhaps easier to understand if you want time between collisions: t = l/v. And of course nu = 1/t. The collision frequency just depends on the material properties of the target and not the beam (obviously velocity of beamed particles but that's not a material property) There is something calle dthe luminosity of the beam and that depends on the number of beam particles per unit time.
