The W-parameter is more sensitive to the annihilation with high momentum core electrons and is defined as the ratio of counts in the wing regions of the peak to the total counts in the peak.
Polarization of the core electrons by the valence electron is important in alkali metal atoms.
Although the valence electrons participate most in forming chemical bonds in molecules and compounds, the energy levels in core electrons are shifted slightly by chemical bonding.
It is also possible to identify the chemical state of the elements both from small shifts in the BEs of core electrons and from larger shifts in the BEs of the valence electrons participating in chemical bonding.
It is also possible to identify the chemical state of the elements both from small shifts in the BEe of core electrons and from larger shifts in the BEs of the valence electrons participating in chemical bonding.
