A Survey of Beam Asymmetries in Semi-exclusive Electron Scattering on 4He and 12C

Creators

Description

A study of the polarized electron beam asymmetry in semi-exclusive (e,e(prime)p) reactions on 4He and 12C over a large kinematic range has been performed. The beam asymmetry A(prime)LT is related to the imaginary part of the longitudinal-transverse interference and therefore it vanishes in reactions proceeding through a channel with a single dominant mechanism. In quasifree nucleon knockout, the helicity asymmetry provides an unambiguous signature for the interference between direct knockout and rescattering amplitudes. The data were taken in April-May 1999 using polarized beams of energies between 2.2 and 4.4 GeV, with the CEBAF Large Acceptance Spectrometer (CLAS) detector located in Hall B at the Jefferson Laboratory, VA. The measured asymmetries compare well with the theoretical predictions
