We have measured the transverse asymmetry A(T') in 3He(e,e(')) quasielastic scattering in Hall A at Jefferson Laboratory with high precision for Q2 values from 0.1 to 0.6 (GeV/c)(2). The neutron magnetic form factor G(n)(M) was extracted based on Faddeev calculations for Q2 = 0.1 and 0.2 (GeV/c)(2) with an experimental uncertainty of less than 2%.
We propose a measurement of the electromagnetic form factor ratio of the neutron, GE /G n M, at high four–momentum transfer values of Q 2 = 5.0, 6.8, and 10.2 GeV2 in double polarized semi-exclusive 3 −→ He(~e,e′n)pp scattering in quasi–elastic kinematics by measuring the transverse asymmetry, A⊥, of the cross section. This quantity can then be used to quickly extract the electric form factor, ...
The Jefferson Lab (JLab) IR Demo Free Electron Laser (FEL) has completed commissioning and is initiating user service. The FEL — a high repetition rate, low extraction efficiency wiggler-driven optical cavity resonator — produces over 1 kW of tuneable light on intervals in a 3–6 μm wavelength range. It is driven by a 35–48 MeV, 5 mA superconducting RF (SRF) based energyrecovering continuous wav...
