Beam spin asymmetry measurements in deeply virtual Compton scattering
<p>Beam Spin 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 …

Triple Coincidence Beam Spin Asymmetry Measurements in Deeply Virtual Compton Scattering
… Laboratory in Fall 2004. I present here Beam Spin Asymmetry (BSA) results for the <em>ep</em> → <em>epγ </em>reaction studied in the E00-110 experiment with fully exclusive triple coincidence <em>H</em>(<em>e</em>, <em>e'γp </em>) detection. I present a re-calibration of the …

Electroproduction of Neutral Pion Off Helium-4
… nuclei. The goal of this work is to extract the beam-spin asymmetry in deeply virtual coherent neutral pion electroproduction, <em>e</em><sup>4</sup>He → <em>e′</em><sup>4</sup>He′π<sup>0</sup>, using the CLAS detector in the experimental Hall B at Thomas Jefferson National Accelerator Facility. …

On Quantum Reflection and The Casimir Effect : Application to atom-surface scattering
… of experimental data obtained with the Atomic Beam Spin Echo (ABSE) spectrometer by scattering 3He from a strongly disordered alpha-quartz dielectric surface and from an atomically rough gold surface under grazing incidence. The data are interpreted in terms of the quantum reflection theory …
