Characteristic X-rays: Direction of Emission?

[fizikx]

Hello physics forum,

I'm running an experiment where characteristic x-ray are produced from an Iron sample, and I was just wondering if these x-rays are emitted in any random direction, or is there a "favored" direction they can be emitted in? Thank you in advance.

Neville.

There have been some studies investigating dependence of yield on the direction relative to different crystallographic planes (i.e., on single crystal targets). I know the intensity is not isotropic, but don't remember much more than that. You'll have to search the literature with some of these keywords to find any numbers.

There is no particular direction of released X-rays after hitting the target(in your case iron). But the rays which are released on this interaction will mixed up with Bremsstrahlung(braking radiation) and released as a sprectrum. its depend on the material what you using at the target side.
hope this cleared for you. contact if you have further queries.
