Question

Which of the following is an Auger transition starting from a hole in 1s levels which would be filled up from the 2p level?

(a) KLM transition

(b) KLL transition

(c) LMN transition

(d) LLM transition

This question was posed to me by my college professor while I was bunking the class.

Enquiry is from Auger Electron Spectroscopy in chapter Electron and Ion Spectrometers of Analytical Instrumentation

Answer 1

Right choice is (b) KLL transition

The best I can explain: KLL transition is an Auger transition starting from a hole in 1s levels which would be filled up from the 2p level. 2p electron would also be emitted.
