We know that when an electron is knocked from the innermost shell of an atom (K - shell), a vacancy is created in the K - Shell. This vacancy in the K - Shell is by an electron falling from an upper shell (usually L-Shell or M-Shell) producing photons due to falling of electron from an upper to a lower orbit. These are called Characteristic X-Rays.
MY QUESTION:
During Electron Capture (or K - Capture) type of β-decay, the nucleus absorbs an inner atomic electron hence converting the nuclear proton to a neutron and emitting an electron neutrino according to the following equation:
My question is that when an electron is absorbed by the nucleus it automatically creates a vacancy in its shell, which needs to be filled. Hence does an electron from an upper shell fill the vacancy and emit characteristic X-Rays (and hence energy in addition to decay energy) or is the complete energy released only in the form of energy of the neutrino ?
