The cross section for the double Compton effect is integrated numerically in the laboratory system, and the effect of the radiative tail to the Compton line is discussed. The double Compton effect is also studied in the c. m. system for the cases in which the energy of one of the emitted photons is much smaller than the electron rest energy or much smaller than the energy of the incident photon. Expressions for the radiative corrections to the total cross section for Compton scattering are obtained in the high-energy approximation to first order in the fine-structure constant. The total cross section for the double Compton effect is computed by numerical integration. The contribution to the absorption coefficient for high-energy photons from double Compton scattering and Compton scattering with the emission and reabsorption of a virtual photon is obtained.

Using modern multiloop calculation methods, we derive the analytical expressions for the total cross sections of the processes e−γ → $ {e}^{-}X\overline{X} with X = μ, γ or e at arbitrary energies. For the first two processes our results are expressed via classical polylogarithms. The cross section of e−γ → e−e−e+ is represented as a one-fold integral of complete elliptic integral K and logarithms. Using our results, we calculate the threshold and high-energy asymptotics and compare them wit...

We study the double Compton (DC) process for a wide range of particle energies, extending previous treatments well beyond the soft photon limit, employing both numerical and analytical methods. This allows us to investigate the physics of the DC process up to the highly relativistic regime relevant to electromagnetic particle cascades in the early Universe and photon-dominated astrophysical plasmas. Generalized exact analytic expressions for the DC emissivity in the soft photon limit are obtaine...

Abstract The cross section of atomic electron Compton scattering γ + e → γ ′ + e ′ was measured in the 4.400–5.475 GeV photon beam energy region by the PrimEx collaboration at Jefferson Lab with an accuracy of 2.6% and less. The results are consistent with theoretical predictions that include next-to-leading order radiative corrections. The measurements provide the first high precision test of this elementary QED process at beam energies greater than 0.1 GeV.

The three-photon Compton effect is studied. An incoming photon undergoes triple scattering off a free electron, which leads to the emission of three entangled photons. We investigate the properties of both the total cross section, assuming a low-energy cutoff for the detected photons, and the differential cross section. Particular emphasis is laid on evaluating polarization-resolved cross sections. The entanglement of the final three-photon state is analyzed.

Abstract The total incoherent scattering cross sections are calculated using relativistic and nonrelativistic incoherent scattering functions for the energy range 1–10,000 keV for low- Z elements (C, O, Ne, S, Ar). The calculated cross sections are compared with tabulated theoretical values and found to be smaller than the tabulated theoretical values with a ratio of 1.86–90.46% in relativistic formalism and 1.82–7.27% in nonrelativistic formalism. The smallest total incoherent scattering cross ...

Coherent and incoherent scattering cross sections have been measured using a high purity germanium detector on elements in the range of Z = 13–50 using 241Am gamma rays. The cross sections have been derived by comparing the net count rate obtained from the Compton peak of aluminum with the elastic/Compton peak of the target element. The measured cross sections for the coherent and incoherent processes are in agreement with the theoretical values.

The study of π0 decay has played an important role in the development of particle physics: The π0→γγ decay provides key insights into the anomaly sector of quantum chromodynamics. In this review, the historical progression of π0 discovery, lifetime measurements, and theory are presented. A new measurement of the π0 radiative width via the Primakoff effect has been made at JLab. The result, Γ(π0→γγ)=7.82±0.14(stat.)±0.17(syst.) eV, is a factor of 2.1 more precise than the currently accepted value...

Modern Monte Carlo codes allow for the calculation of ion chamber specific beam quality correction factors kQ, which are needed for dosimetry in radiotherapy. While statistical (type A) uncertainties of the calculated data can be minimized sufficiently, the influence of systematic (type B) uncertainties is mostly unknown. This study presents an investigation of systematic uncertainties of Monte Carlo-based kQ values for a NE2571 thimble ion chamber, calculated with the EGSnrc system. Starting wi...

Photon (x-ray, gamma-ray, bremsstrahlung) mass attenuation coefficients, μ/ρ, are among the most widely used physical parameters employed in medical diagnostic and therapy computations, as well as in diverse applications in other fields such as nuclear power plant shielding, health physics and industrial irradiation and monitoring, and in x-ray crystallography. This review traces the evolution of this data base from its empirical beginnings totally derived from measurements beginning in 1907 by ...

This paper presents a numerical investigation of the effective point of measurement of thimble ionization chambers in megavoltage photon beams using Monte Carlo simulations with the EGSNRC system. It is shown that the effective point of measurement for relative photon beam dosimetry depends on every detail of the chamber design, including the cavity length, the mass density of the wall material, and the size of the central electrode, in addition to the cavity radius. Moreover, the effective poin...
