INDIA <p style="text-align: justify;">We theoretically investigated photon excited K<sub>a</sub> x-ray satellite spectra of Si and SiO<sub>2</sub> using plasmon theory. The KaL<sup>1</sup>/ KaL<sup>0</sup> and KaL<sup>2</sup> / KaL<sup>0</sup> intensity ratio are found to be agreed well with experimentally observed values. In the calculation of relative intensity; intrinsic, extrinsic and their relative contributions have been discussed.<br /> &nbsp;</p> https://ultraphysicalsciences.org/paper/1344/ X-ray satellites energy separation bulk and surface plasmon relative intensity.
