Multiple Scattering Theory of Photoemission
for Spherical and Non-Spherical Atomic Scattering Potentials
The final wavefunction Yf after photoexcitation and scattering:
f0i = Initial core level (localized in one cell)
Vrad = Incident-light perturbation potential (dipole approximation)
Tj = Scattering Matrix of j-cell
Gem = Green function of the cell from which photoemission takes place
G0 = Free-electron Green function (if there is no hole)
The space is divided into individual cells:
