Abstract
Single spin azimuthal asymmetries A(LT') were measured at Jefferson Lab using 2.2 and 4.4 GeV longitudinally polarised electrons incident on He-4 and C-12 targets in the CLAS detector. ALT' is related to the imaginary part of the longitudinal-transverse interference and in quasifree nucleon knockout it provides an unambiguous signature for final state interactions (FSI). Experimental values of ALT' were found to be below 5 %, typically \A(LT')\ less than or equal to 3 % for data with good statistical precision. Optical model in eikonal approximation (OMEA) and relativistic multiple-scattering Glauber approximation (RMSGA) calculations are shown to be consistent with the measured asymmetries.
