چکیده

We present data on the inclusive scattering of polarized electrons from a polarized 3He target at energies from 0.862 to 5.06 GeV, obtained at a scattering angle of 15.5 degrees. Our data include measurements from the quasielastic peak, through the nucleon resonance region, and beyond, and were used to determine the virtual photon cross-section difference sigma(1/2)-sigma(3/2). We extract the extended Gerasimov-Drell-Hearn integral for the neutron in the range of four-momentum transfer squared Q2 of 0.1-0.9 GeV2.

The Q2-dependence of the generalised Gerasimov–Drell–Hearn integral for the proton HERMES Collaboration

The dependence on Q2 (the negative square of the 4-momentum of the exchanged virtual photon) of the generalised Gerasimov–Drell–Hearn integral for the proton has been measured in the range 1.2 GeV2 < Q2 < 12 GeV2 by scattering longitudinally polarised positrons on a longitudinally polarised hydrogen gas target. The contributions of the nucleon-resonance and deep inelastic regions to this integr...

Q–Dependence of the Gerasimov-Drell-Hearn Sum Rule

We test the Gerasimov-Drell-Hearn (GDH) sum rule numerically by calculating the total photon absorption cross sections σ1/2 and σ3/2 on the nucleon via photon excitation of baryon resonances in the constituent quark model. A total of seventeen, low-lying, non-strange baryon resonances are included in this calculation. The transverse and longitudinal interference cross section, σ 1/2, is found t...

Measurement of the Gerasimov-Drell-Hearn Integral at low on the Neutron and Deuteron

We propose a precision measurement at low momentum transfer ( GeV ) of the Gerasimov-Drell-Hearn integral for the deuteron using the Hall B CLAS detector. By combining these data with the proton data taken under similar conditions (approved E03-006) we can extract the GDH integral on the neutron. These data will provide a benchmark for neutron Chiral Perturbation Theory ( PT) calculations. Also...
