Hello! I've been doing a lot of research on cloud chambers recently, and I've come up with a quite a few questions on the behavior of certain types of ionizing radiation: 1) For a start, I assume that gamma-rays and X-rays will induce Compton scattering inside the cloud chamber. Would a photon realistically undergo the compton effect multiple times? My guess: Yes. However, after a few times, the photon will no longer possess enough energy to undergo the compton effect. 2) I know the compton scattering equation: λ' - λ = (h/mc) (1 - cosθ) Unfortunately, I can only realistically approximate the value for λ, while I have no way to find the value of θ or λ' based on the trails in the cloud chamber. Is there any way I could figure out or at least estimate such values? 3) The trails caused by beta decay in the cloud chamber bend much less than electrons created through compton scattering by gamma rays. Is there any scientific reason for this phenomena? I'm assuming that my "compton scattering assumption" is accurate. If it isn't I would appreciate if a better explanation could be provided. I'm not sure if this should have gone in the homework section. If it should have, sorry in advance! Thanks for the help!
