Multiple X-ray Emission during Electron Capture

In an atomic environment, a $$\beta$$-decay process competing with positron emission is electron capture, in which the nucleus absorbs one of its cloud of atomic electrons, emitting only a neutrino.

$$p+e^-\rightarrow n+\nu_e$$ Such a process often called K-capture since $$e^-$$most likely to come from the innermost K-shell of atomic electrons.

An outer electron replaces the "missing" electron. An x-ray, equal in energy to the difference between the two electron shells, is emitted. See the following.

Now as the outer orbital electron takes place the misplaced one, Isn't another position is vacant? Then What would happen? Is the upper once again take the place of the lower site? Then Does this process repeat again and again? Does that imply there would be many x-ray emissions?

• I don't follow what position you mean when you say "another position is vacant". After capture there is a single position on an inner shell vacant. An outer shell electron drops down into this position, filling it. Where is your "vacant" position? Apr 22, 2021 at 16:55
• I mean, if the vacancy in the atomic k-shell is filled by an electron falling from L-shell. Then they will be vacancies created in L-shell as the electron from their is jumped to k-shell. Apr 22, 2021 at 17:06
• Why did you change the title? Gammas are emitted by the nucleus as it de-excites from internal excited states. X-rays are the result of atomic electron transitions. Your text asks about x-rays. Apr 22, 2021 at 17:58
