He→3(e→e′) quasielastic asymmetry
(1993-01)
Measurements of the spin-dependent asymmetry in scattering longitudinally polarized electrons from polarized He3 at quasielastic kinematics are reported. The measurements were made at two kinematics and spin angles, one ...
Exclusive 16O(γ,π-p) reaction in the Δ resonance region
(1992-08)
We report the first exclusive (γ,π-p) measurements on a complex nucleus. The 16O(γ,π-p) reaction was measured at pion laboratory angles of 64° and 120°. Coincident protons were detected over the quasifree angular correlation ...
Reaction 58Ni(π+,pp) at Tπ+=160 MeV
(1990-05)
The reaction 58Ni(π+,pp) was studied with good energy resolution for an incident pion energy of 160 MeV. The angular correlation of the outgoing protons was measured for θlab=30°, 75°, and 130°. From these angular correlations ...
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 ...
Proton propagation in nuclei studied in the (e,e’p) reaction
(1992-02)
Proton propagation in nuclei was studied using the (e,e’p) reaction in the quasifree region. The coincidence (e,e’p) cross sections were measured at an electron angle of 50.4° and proton angles of 50.1°, 58.2°, 67.9°, and ...
Transverse Beam Spin Asymmetries in Forward-Angle Elastic Electron-Proton Scattering
(American Physical Society, 2007-07-31)
We have measured the beam-normal single-spin asymmetry in elastic scattering of transversely polarized 3 GeV electrons from unpolarized protons at Q2=0.15, 0.25 (GeV/c)2. The results are inconsistent with calculations ...
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 ...
Measurement of the spin-dependent asymmetry in 3→(e→,e′) inelastic scattering at low energy transfer
(1995-09)
We present the results of a measurement of the spin-dependent asymmetry in 3→(e→,e′) inelastic scattering at kinematics on the low-energy transfer side of the quasielastic peak, including the region near the breakup ...
Transverse-Longitudinal Asymmetry in the Quasielastic 3He⃗(e⃗, e′) Reaction
(The American Physical Society, 1995-01-30)
The transverse-longitudinal asymmetry ATL′ in 3He⃗(e⃗, e′) quasielastic scattering at momentum transfer Q2=0.14 (GeV/c)2 has been measured to be 1.52 ± 0.55(stat) ± 0.15(syst)%. The plane wave impulse approximation (PWIA) ...
Tensor polarization in elastic electron-deuteron scattering in the momentum transfer range 3.8≤Q≤4.6 fm-1
(1994-05)
The tensor polarization of the recoil deuteron in elastic electron-deuteron scattering has been measured at the Bates Linear Accelerator Center at three values of four-momentum transfer Q=3.78, 4.22, and 4.62 fm-1, ...
