Core excitation spectra of CH4 and SiH4

Abstract

One-center Hartree-Fock calculations have been performed both on the ground and on some of the highly excited states of CH4 and SiH4. The calculations are in reasonable agreement with the salient features of recent soft x-ray absorption experiments on SiH4 [W. Hayes and F. C. Brown, Phys. Rev. A 6, 21 (1972)]; W. Hayes, F. C. Brown, and A. B. Kunz, [Phys. Rev. Lett. 27, 774(1971)] and on CH4 [H. U. Chun, Phys. Lett. A 30, 445 (1969)].
