Extrinsic and Intrinsic Effects in Photon Induced K X-Ray Satellite Spectra of Al and Al2O3

The origin of KaL1 and KaL2 satellite spectra of Al and Al2O3 have been explained using plasmon theory with new approach by considering relative interference between intrinsic and extrinsic effects. The results have been probed by comparing to the relative satellite yields obtained by photo- ionization and other experimental estimates. We also review existing calculations and measurements found that these satellites are due to surface plasmon excitations.
