Characteristic X-rays, intensity ratios

Click For Summary
SUMMARY

The discussion centers on the intensity ratios of characteristic X-rays, specifically the Kalpha to Kbeta transitions from an X-ray tube. Participants agree that Kalpha transitions are generally more probable than Kbeta transitions, with a typical intensity ratio of about 2 to 1 favoring Kalpha. However, one participant noted an observation from an X-ray diffraction spectrum indicating that Kbeta may appear more intense than Kalpha, leading to confusion regarding the expected ratios. Clarification was sought on whether the reference was to a diffraction pattern or a fluorescence spectrum.

PREREQUISITES
  • Understanding of X-ray tube operation and characteristics
  • Knowledge of Kalpha and Kbeta transitions in X-ray emission

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.

Looking forwards to reading your wise thoughts!

about 2 to 1 usually. The KA transition is more probable. I don't understand how you could deduce something contrary to this, especially from a diffraction pattern. did you mean fluorescence spectrum?
