Book excerpt: A first measurement of the longitudinal asymmetry of deep-inelastic scattering of polarized electrons from a polarized 3He target at energies ranging from 19 to 26 GeV has been performed at SLAC. The spin-structure function of the neutron g1(superscript n) has been extracted from the measured asymmetries allowing for a test of the Ellis-Jaffe and Bjorken sum rules. The Quark Parton Model (QPM) interpretation of the nucleon spin-structure function is examined in light of the new results.

Book excerpt: A measurement of the nucleon spin asymmetries from deep inelastic scattering of polarized electrons by polarized [sup 3]He has been performed. The neutron spin structure function g[sub 1][sup n] is extracted and used to test the Bjorken sum rule. The neutron integral assuming a simple Regge theory extrapolation at low x is [integral][sub 0][sup 1]g[sub 1][sup n](x)dx = [minus]0.022 [plus minus] 0.011. Combined with the EMC proton results, the Bjorken sum rule predicts a neutron integral of [integral][sub 0][sup 1]g[sub 1][sup n](x)dx = [minus]0.065 [plus minus] 0.018.

Download or read book Measurement of the 3He Spin Structure Functions in the Resonance Region written by and published by . This book was released on 2006 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the biggest challenges in the study of the nucleon structure is the understanding of the transition from partonic degrees of freedom to hadronic degrees of freedom. In 1970, Bloom and Gilman noticed that structure function data taken at SLAC in the resonance region average to the scaling curve of deep inelastic scattering (DIS). Early theoretical interpretations suggested that these two very different regimes can be linked under the condition that the quark-gluon and quark-quark interactions are suppressed. Substantial efforts are ongoing to investigate this phenomenon both experimentally and theoretically. Quark-hadron duality has been confirmed for the unpolarized structure function F2 of the proton and the deuteron using data from the experimental Hall C at Jefferson Lab (JLab). Indications of duality have been seen for the proton polarized structure function g1 and the virtual photon asymmetry A1 at JLab Hall B and HERMES. Because of the different resonance behavior, it is expected that the onset of duality for the neutron will happen at lower momentum transfer than for the proton. Now that precise spin structure data in the DIS region are available at large x, data in the resonance region are greatly needed in order to test duality in spin-dependent structure functions. The goal of experiment E01-012 was to provide such data on the neutron (3He) in the moderate momentum transfer (Q2) region, 1.0 Qsup2/sup 4.0 (GeV/csup2/sup), where duality is expected to hold. The experiment ran successfully in early 2003 at Jefferson Lab in Hall B. It was an inclusive measurement of longitudinally polarized electrons scattering from a longitudinally or transversely polarized sup3/supHe target. Asymmetries and cross section differences were measured in order to extract the sup3/supHe spin structure function gsub1/sub and virtual photon asymmetry Asub1/sub in the resonance region. A test of quark-hadron duality has then been performed for the sup3/supHe and neutron structure functions. The study of spin duality for the neutron will provide a better understanding of the mechanism of the strong interaction. Moreover, if duality is well understood, our resonance data will bring information on the high x region where theoretical predictions for A

Available in PDF, EPUB and Kindle. Book excerpt: The asymmetry A2(x, Q2) and structure function g2(x, Q2) were measured for the neutron using deep inelastic electron scattering. The measurement was made using the 50 GeV longitudinally polarized electron beam at the Stanford Linear Accelerator Center. The target consisted of gaseous 3He which was polarized through spin exchange with optically pumped rubidium vapor. Data were taken simultaneously with two magnetic spectrometers fixed at 2.75{sup o} and 5.5{sup o} scattering angles, covering a combined kinematic range of 0.014 d"x d"0.7 and 1.0 d"Q2 d"17.0 (GeV/c)2. The A2 data were found to be well bounded by the positivity constraint.

Book excerpt: Experiment E97-110 was performed at the Thomas Jefferson National Accelerator Facility in Hall A to provide a precise measurement of the moments of the neutron and $^{3}$He spin structure functions. A longitudinally-polarized electron beam was scattered from a longitudinally or transversely polarized $^{3}$He target. The extended Gerasimov-Drell-Hearn integral and other moments of the neutron and $^{3}$He spin structure functions were extracted at very low momentum transfers (0.02 $

Available in PDF, EPUB and Kindle. Book excerpt: The spin dependent cross sections,?{sup T}12 and?{sup T}32, and asymmetries, A{sub {parallel}} and A{sub {perp}}, for 3He have been measured at the Jefferson Lab's Hall A facility. The inclusive scattering process 3{vec He}({vec e}, e)X was performed for initial beam energies ranging from 0.86 to 5.1 GeV, at a scattering angle of 15.5°. Data includes measurements from the quasielastic peak, resonance region, and the deep inelastic regime. An approximation for the extended Gcrasimov-Drell-Hcarn integral is presented at a 4-momentum transfer Q2 of 0.2-1.0 GeV2 . Also presented are results on the performance of the polarized 3He target. Polarization of 3He vvas achieved by the process of spin-exchange collisions with optically pumped rubidium vapor. The 3He polarization was monitored using the NMR technique of adiabatic fast passage (AFP). The average target polarization was approximately 35% and was determined to have a systematic uncertainty of roughly ±4% relative.
