Title: First measurement of proton's charge form factor at very low Q2 with initial state radiation

Abstract

Here we report on a new experimental method based on initial-state radiation (ISR) in e–pscattering, which exploits the radiative tail of the elastic peak to study the properties of electromagnetic processes and to extract the proton charge form factor (G$$p\atop{E}$$) at extremely small Q². The ISR technique was implemented in an experiment at the three-spectrometer facility of the Mainz Microtron (MAMI). This led to a precise validation of radiative corrections far away from elastic line and provided first measurements of G$$p\atop{E}$$ for 0.001 ≤Q²≤0.004 (GeV/c)².

High-precision determination of the electric and magnetic form factors of the proton

Journal Article Bernauer, Jan C ; Laboratory for Nuclear Science, MIT, Cambridge, MA 02139 - AIP Conference Proceedings

New precise results of a measurement of the elastic electron-proton scattering cross section performed at the Mainz Microtron MAMI are presented. About 1400 cross sections were measured with negative four-momentum transfers squared up to Q{sup 2} = (GeV/c){sup 2} with statistical errors below 0.2%. The electric and magnetic form factors of the proton were extracted by fits of a large variety of form factor models directly to the cross sections. The form factors show some features at the scale of the pion cloud. The charge and magnetic radii are determined to be r{sub E}{sup 2} rpost={sup >>1/2} 0.879(5){sub stat.}(4){sub syst.}(2){submore »« less

First measurement of the electric formfactor of the neutron in the exclusive quasielastic scattering of polarized electrons from polarized {sup 3}He

Journal Article Meyerhoff, M ; Eyl, D ; Frey, A ; ... - AIP Conference Proceedings

A first measurement of the asymmetry in quasielastic scattering of longitudinally polarized electrons from a polarized {sup 3}He gas target in coincidence with the knocked out neutron is reported. This measurement was made feasible by the cw beam of the 855 meV Mainz Microtron MAMI. It allows a determination of the electric formfactor of the neutron {ital G}{sup {ital n}}{sub {ital E}} independent of binding effects to first order. At {ital {bar Q}}{sup 2}=0.31 (GeV/c){sup 2} two asymmetries {ital {bar A}}{sub {parallel}}({ital {rvec S}}{sub He}{parallel}{ital {rvec q}}) and {ital {bar A}}{sub {perpendicular}}({ital {rvec S}}{sub He}{perpendicular}{ital {rvec q}}) have been measuredmore »« less

Determination of the neutron electric formfactor in quasielastic collisions of polarized electrons with {sup 3}He and {sup 2}D. Collaboration A3 at MAMI

Journal Article Andresen, H G ; Annand, J R.M. ; Aulenbacher, K ; ... - AIP Conference Proceedings

The determination of the neutron electric formfactor from quasielastic reactions {sup 3}{ital {rvec H}e}({ital {rvec e}},{ital e}{prime}{ital n}) and {ital D}({ital {rvec e}},{ital e}{prime},{ital {rvec n}}) respectively is one of the present goals of experiments with polarized electrons at the Mainz race track microtron MAMI. A GaAsP-photoelectron source is used at MAMI to get an 855 MeV electron beam spinpolarized to a degree of 35% at a current of 10 {mu}A. Polarized {sup 3}He-nuclei are produced by optical pumping metastable {sup 3}He. Scattered electrons are detected in coincidence with the recoil neutrons, the transverse spinpolarization of the neutrons may bemore »« less

Precision Measurement of the proton neutral weak form factors at Q² ~ 0.1 GeV²

Thesis/Dissertation Kaufman, Lisa J.

This thesis reports the HAPPEX measurement of the parity-violating asymmetry for longitudinally polarized electrons elastically scattered from protons in a liquid hydrogen target. The measurement was carried out in Hall A at Thomas Jefferson National Accelerator Facility using a beam energy E = 3 GeV and scattering angle <θ{sub lab}> = 6°. The asymmetry is sensitive to the weak neutral form factors from which we extract the strange quark electric and magnetic form factors (Gmore »« less
