Probably a stupid question but when the energy of x ray photons striking atomic electrons increase, why is it that the probability of photoionisation decreases?
I mean, obviously there are absorption edges corresponding to the K, L, M etc edges but the *general* trend is that the the absorption probability decreases with increasing photon energy. Why is this the case?
