Deuteron compton scattering below pion threshold
… at MAX-lab in Lund, Sweden to study photon scattering from the deuteron and extract the neutron polarizabilities. The deuteron Compton scattering cross section was measured at laboratory angles of $60^o$, $120^o$, and $150^o$ for photon energies from 70 - 112 MeV. The photons were scattered …

Some Aspects of Deeply Virtual Compton Scattering
<p>We consider different aspects of the virtual Compton amplitude in QCD on two examples: small-x physics accessible in the Regge regime and twist-3 approximation in the description of DVCS through the general parton distributions. Using this model, we give an estimate for the cross section of …

Virtual Compton Scattering Processes in Quantum Chromodynamics
… of perturbative QCD to deeply virtual Compton scattering and hard exclusive meson electroproduction processes require a generalization of usual Parton distributions for the case when long-distance information is accumulated in nonforward matrix elements [special characters omitted] of …

Proton Compton scattering with polarized γ rays
Proton Compton scattering has been studied from 220 to 330 MeV at 90 degree center of mass scattering angle with the polarized photon beam at LEGS. Compton scattering is an important probe of the nucleon structure and its excited states. Polarization degrees of freedom reveal more information than …

Compton scattering from the deuteron at intermediate energies
Elastic and quasi-elastic photon scattering from the deuteron were studied in the context of the polarizability of the neutron. We have measured the elastic and quasi-elastic cross sections for the scattering of tagged photons from a liquid deuterium target at $E\gamma$ = 50 MeV and scattering …

Three-dimensional simulation of coherent inverse Compton scattering
… for characterizing the properties of inverse Compton scattering (ICS) sources where the electron density varies on the order of the laser wavelength. Finally, an analysis of the emission characteristics for an example ICS source with coherent emission at 10 nm wavelength is included. The …

Beam spin asymmetry measurements in deeply virtual Compton scattering
… Asymmetry (BSA) is studied in the Deeply Virtual Compton Scattering (DVCS) using CLAS detector at Jefferson Lab and longitudinally polarized electron beam with 4.8 GeV energy. This asymmetry is directly proportional to the imaginary part of the scattering amplitude, which relates it to the …

Deeply Virtual Compton Scattering at Hall A, Jefferson Lab
… of a quark-gluon system. Deeply Virtual Compton Scattering (DVCS) is understood to be the simplest and cleanest process to access GPDs. Even though the exclusive DVCS is simple to understand, the experimental process however, is complex with the Bethe-Heitler and Associated DVCS being in …

Deeply Virtual Compton Scattering off unpolarised deuterium at HERMES
… focused on measurements of the Deeply Virtual Compton Scattering (DVCS) process. These measurements are sensitive to GPDs, allowing further experimental constraints to be made on the components of nucleon spin. In the Winter shutdown period 2005-2006 HERMES was upgraded with a Recoil Detector …

Neutron Compton scattering from hydrogen and perovskite oxide interfaces
… we investigate two independent topics: neutron Compton scattering from hydrogen and perovskite oxide interfaces. Part one is an investigation of the scattering of high energy neutrons from hydrogen compounds. The motivation for this investigation stems from neutron Compton scattering …

Measurements of Compton Scattering on the Proton at 2--6 GeV
"Similar to elastic electron scattering, Compton scattering on the proton at high momentum transfers (and high p⊥) can be an effective method to study its short-distance structure. An experiment has been carried out to measure the cross sections for Real Compton Scattering (RCS) on the proton for …

Differential Cross Sections for Compton Scattering Off the Proton at 185 MEV
A complete angular distribution of Compton scattering off the proton was measured at average laboratory bremsstrahlung energy of 185 MeV. The experiment was per-formed at the Saskatchewan Accelerator Laboratory using the new high duty factor elec-tron beam. The scattered photons were observed with …
