Ionization resonant orbital rearrangement

RESONANT ORBITAL REARRANGEMENT DURING F Is IONIZATION OR DECAY PROCESS... 

The present author proposed an the approximation method to explain the deviation of the X-ray satellite spectra intensity distributions from those described by eqs.(2),(5),(8) and (10), which we call Resonant Orbital Rearrangement (ROR) [6]. ROR was first used to explain the anomalous intensity distributions in F Ka satellite spectra which are emitted from a series of alkali-fluorides. Here resonance occurs during F Is ionization between the highest occupied molecular orbital (HOMO) in the KT. state and HOMO in the (K L +3s) state corresponding to the lowest unoccupied molecular orbital (LUMO) in the K L state. This leads to a reduction in the K L X-ray satellite intensity and to an increase in the K L X-ray diagram line intensity. Here (K L +3s) denotes the state with one vacancy in K shell and one vacancy in L shell and one electron in a 3s... 

Fig.l2. Resonant Orbital Rearrangement between the HOMO in the K L state and the HOMO in the (K L +3s) state for an element with Z=9 or less. This is a kind of excitation of an electron from the HOMO to the LUMO during Is ionization.
