Cross section measurements of charged pion photoproduction in hydrogen and deuterium from 1.1 to 5.5 GeV
(2005-04)
The differential cross sections for the γn→π-p and the γp→π+n processes were measured at Jefferson Lab. The photon energies ranged from 1.1 to 5.5 GeV, corresponding to center-of-mass energies from 1.7 to 3.4 GeV. The pion ...
Quasielastic (e,e′p) reaction on 12C,56Fe, and 197Au
(2003-12)
We report the results from a systematic study of the quasielastic (e,e′p) reaction on 12C, 56Fe, and 197Au performed at Jefferson Lab. We have measured nuclear transparency and extracted spectral functions (corrected for ...
Evidence for virtual Compton scattering from the proton
(1995-11)
In virtual Compton scattering an electron is scattered off a nucleon such that the nucleon emits a photon. We show that these events can be selected experimentally, and present the first evidence for virtual Compton ...
Separated spectral functions for the quasifree 12C(e,e′p) reaction
(2000-05)
A separation of the longitudinal and transverse 12C(e,e′p) cross sections in the quasifree region has been performed in parallel kinematics at Q2 of 0.64 and 1.8 GeV2 for initial proton momentum <80 MeV. The separated ...
Coherent π0 photoproduction on the deuteron up to 4 GeV
(1999-09)
The differential cross section for 2H(γ,d)π0 has been measured at deuteron center-of-mass angles of 90° and 136°. This work reports the first data for this reaction above a photon energy of 1 GeV, and permits a test of the ...
Inclusive electron scattering from nuclei at x≃1
(1996-05)
The inclusive A(e,e′) cross section for x≃1 was measured on 2H, C, Fe, and Au for momentum transfers Q2 from 1 to 6.8 (GeV/c)2. The scaling behavior of the data was examined in the region of transition from y scaling to x ...
Nuclear transparency with the γn⃗π-p process in 4He
(2003-08)
We have measured the nuclear transparency of the fundamental process γn⃗π-p in 4He. These measurements were performed at Jefferson Lab in the photon energy range of 1.6–4.5 GeV and at θcmπ=70° and 90°. These measurements ...
Two-Body Photodisintegration of the Deuteron up to 2.8 GeV
(The American Physical Society, 1995-01)
Measurements were performed for the photodisintegration cross section of the deuteron for photon energies from 1.6 to 2.8 GeV and center-of-mass angles from 37° to 90°. The measured energy dependence of the cross section ...
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 ...
