Polarized beam −→γ p Compton scattering provides a theoretically clean way to extract the isovector parity violating pion-nucleon coupling constant h (1) πNN . This channel is more tractable experimentally than the recently proposed extraction of h (1) πNN from the Bedaque-Savage process — polarized target γ −→p compton scattering. The leading parity violating effect is calculated using Heavy B...

Without collisions, the largest contribution to the beam lifetime in LEP is Compton scattering off thermal photons. Even if only a few particles are scattered in a single pass, the potential background generated could make this effect important for the NLC as well. We used a modified version of the tracking program DIMAD, which includes a Monte Carlo simulation for the Compton scattering on the...

The Sunyaev-Zel’dovich effect causes a change in the apparent brightness of the Cosmic Microwave Background Radiation towards a cluster of galaxies or any other reservoir of hot plasma. Measurements of the effect provide distinctly different information about cluster properties than X-ray imaging data, while combining X-ray and Sunyaev-Zel’dovich effect data leads to new insights into the struc...

The Kompaneets theory of photon kinetic evolution due to the Compton effect in the absence of absorption and emission is extended to the case of the Vlasov plasma wave oscillations. Under the assumption that the electron distribution function at equilibrium is perturbed by a solution of the linearised Vlasov equation in the long-wavelength limit, a solution of the Kompaneets kinetic equation fo...

We consider the effect of Compton scattering by a Thomson-thick, low-temperature, plasma cloud surrounding the compact object in the binary system Cyg X-3 on its X-ray energy and power spectra. The presence of such a cloud was earlier inferred from the energy-independent orbital modulation of the X-ray flux and the lack of high frequencies in its power spectra. Here, we consider the effect of C...

Introduction: Unfolding X-ray spectrum is a powerful tool for quality control of X-ray tubes. Generally, the acquisition of the X-ray spectrum in diagnostic radiology departments is complicated and difficult due to high photon flux. Measurement of x ray spectra using radiation detectors could not be performed accurately, because of the pulse pile up. Therefore, indirect methods...

When gamma-rays emerge from a central source they may undergo Compton scattering in surrounding matter. The resulting Compton-scattered electrons radiate. Coherent radiation by such Compton electrons follows nuclear explosions above the Earth's atmosphere. Particle acceleration in instabilities produced by Compton electron currents may explain the radio emission of SN1998bw. Bounds on coherent ...
