Momentum transfer dependence of nuclear transparency from the quasielastic 12C(e,e’p) reaction
(1994-03)
The cross section for quasielastic 12C(e,e’p) scattering has been measured at momentum transfer Q2=1, 3, 5, and 6.8 (GeV/c)2. The results are consistent with scattering from a single nucleon as the dominant process. The ...
Quasifree (e,e′p) Reactions and Proton Propagation in Nuclei
(American Physical Society, 1998-06-08)
The ( e,e′p) reaction was studied on targets of C, Fe, and Au at momentum transfers squared Q2 of 0.6, 1.3, 1.8, and 3.3 GeV2 in a region of kinematics dominated by quasifree electron-proton scattering. Missing energy and ...
Exclusive Electron Scattering from Deuterium at High Momentum Transfer
(American Physical Society, 1995-06-12)
Cross sections are presented for the reaction 2H(e,e′p)n for momentum transfers in the range 1.2≤Q2≤6.8(GeV/c)2 and for missing momenta from 0 to 250 MeV/c. The longitudinal-transverse interference structure function has ...
Cross-Section Measurement of Charged-Pion Photoproduction from Hydrogen and Deuterium
(American Physical Society, 2003-06-11)
We have measured the differential cross section for the γn→π-p and γp→π+n reactions at θc.m.=90° in the photon energy range from 1.1 to 5.5 GeV at Jefferson Lab (JLab). The data at Eγ≳3.3 GeV exhibit a global scaling ...
Measurements of Deuteron Photodisintegration up to 4.0 GeV
(American Physical Society, 1998-11-23)
The first measurements of the differential cross section for the d(γ,p)n reaction up to 4.0 GeV were performed at the Continuous Electron Beam Accelerator Facility (CEBAF) at Thomas Jefferson Laboratory. We report the cross ...
Separation of the Longitudinal and Transverse Cross Sections in the p(e, e′K+)Λ and p(e, e′K+)Σ0 Reactions
(2003-05)
We report measurements of cross sections for the reaction p(e,e′K+)Y, for both the Λ and Σ0 hyperon states, at an invariant mass of W =1.84 GeV and four-momentum transfers 0.5 < Q2 < 2 (GeV/c)2. Data were taken for three ...
Longitudinal Electroproduction of Charged Pions from 1H, 2H, and 3He
(American Physical Society, 2001-11-12)
Separated longitudinal and transverse cross sections for charged pion electroproduction from 1H, 2H, and 3He were measured at Q2 = 0.4(GeV/c)2 for two values of the invariant mass, W = 1.15GeV and W = 1.60GeV, in a search ...
Determination of the Charged Pion Form Factor at Q2=1.60 and 2.45 (GeV/c)2
(2006-11)
The 1H(e,e′π+)n cross section was measured at four-momentum transfers of Q2=1.60 and 2.45 GeV2 at an invariant mass of the photon nucleon system of W =2.22 GeV. The charged pion form factor (Fπ) was extracted from the data ...
Determination of the Pion Charge Form Factor at Q2=1.60 and 2.45 (GeV/c)2
(American Physical Society, 2006-11-10)
The 1H(e,e′π+)n cross section was measured at four-momentum transfers of Q2=1.60 and 2.45 GeV2 at an invariant mass of the photon nucleon system of W=2.22 GeV. The charged pion form factor (Fπ) was extracted from the ...
Measurement of the neutron magnetic form factor from inclusive quasielastic scattering of polarized electrons from polarized 3He
(1994-08)
We report a measurement of the asymmetry in spin-dependent quasielastic scattering of longitudinally polarized electrons from a polarized 3He target. The neutron magnetic form factor GMn has been extracted from the measured ...
