Abstract
To assess the contribution of Doppler broadening and examine theCompton profile, the Compton energy absorption cross sections aremeasured and calculated using formulas based on a relativisticimpulse approximation. The Compton energy-absorption crosssections are evaluated for different elements (Fe, Zn, Ag, Au and Hg)and for a photon energy range (1 - 100 keV). With using these crosssections,the Compton component of the mass–energy absorptioncoefficient was derived, where the electron momentum prior to thescattering event caused a Doppler broadening of the Compton line.Also, the momentum resolution function was evaluated in terms ofincident and scattered photon energy and scattering angle. The resultsof cross sections for the coherent and incoherent processes arecompared with theoretical values and reported values of otherresearchers. The present results are in agreement with the theoreticalvalues.
Highlights
Compton effect is a scattering of gamma or x-ray waves by a charged particle in which a portion of its energy is given to the charged particle in an elastic collision
Compton energy absorption cross sections are calculated using the formulas based on a relativistic impulse approximation to assess the contribution of Doppler broadening and to examine the Compton profile literature and explore what, if any, effect our knowledge of this line broadening has on the Compton component in terms of mass–energy absorption coefficient
The Compton profiles J(Q) are calculated theoretically using the HF wave functions which are used for the Compton profile on the computations of x-ray cross sections and attenuation coefficients
