Abstract

Relaxation of the wavefunctions of electrons in the region of a hole formed in an interband transition in a solid leads to a shift of the interband transition energy relative to that which would be predicted by a band structure calculation fit to fermi surface parameters. The theory of this relaxed orbital correction (ROC) is set up in terms of a Slater Koster model in which relaxed atomic and molecular cluster energies are introduced as parameters. Using this model a sum rule is found which gives the effect of band structure on the ROC for a core state hole. A perturbation theory is made of the effects of hole recoil for valence or d-band holes.
