When a K shell X ray is emitted due to transition of electrons from upper states to K shell vacancy, is there any change of electronic wave-function of K shell at the position of the nucleus? Any theory or mode to calculate the change?
The naif atomic shell-model (at undergraduated level) assumes that when you removes one electron "from the K-shell" it is followed by the emission of the
K X-ray leaving so a vacancy in other shell. Therefore, the K-shell remains full and the effect of the upper vacancy do not change the K-shell wave-function.
This should be true at the rough level of the shell-model
I have to contradict. Up to Z = 30 the main process is the emission of auger electrons. not of X-rays (X-L). But that´s no answer to the original question.
My question is in the timescale where K shall vacancy still persist and the electron from other shell have not undergo transition to K shell. In the timescale before 10-18 sec, when the vacancy still persists , does the K shell electronic wavefunction at the position of the nucleus is different from filled K shell wavefunction?
