# Characteristic X-rays, intensity ratios

Hi!

What can be said about the intensity ratios of characteristic X-rays (Kalpha to Kbeta ) originating from a X-ray tube? I mean roughly and in general, not for some very specific anode material.

I first thought that K-L (Kalpha) transitions would be more likely to happen than K-M:s (Kbeta). Then I had a look at a X-ray diffraction spectrum, and it seems Kbeta is quite a bit more intense than Kalpha.
