Compton-Profile Measurements ofN2,O2, and Ne Using Silver and Molybdenum X-Rays

Abstract

Compton-profile measurements have been performed on ${\mathrm{O}}_2$, ${\mathrm{N}}_2$, and Ne using silver and molybdenum radiation. An approach is outlined to correct for the breakdown of the impulse approximation for the $1s$ core electrons. A detailed relationship involving experimental corrections is specified by which one can relate the experimentally measured intensity to the Compton profile. Good agreement is found between the silver and molybdenum results on the long-wavelength side of the Compton profile. Comparison of the Ne experimental results both with Hartree-Fock calculations and calculations which include non-Hartree-Fock correlation effects show that within the experimental error agreement is obtained with the latter calculation. The experimental results for ${\mathrm{N}}_2$ and ${\mathrm{O}}_2$ are compared with theoretical calculations.
