Measurement of the Target-Normal Single-Spin Asymmetry in Deep-Inelastic Scattering from the Reaction He3↑ ( e,e' ) X

Measurement of the Target-Normal Single-Spin Asymmetry in Deep-Inelastic Scattering from the Reaction He3↑ ( e,e' ) X

We report the first measurement of the target single-spin asymmetry in deep-inelastic scattering from the inclusive reaction 3He↑(e,e')X on a 3He gas target polarized normal to the lepton plane. Assuming time-reversal invariance, this asymmetry is strictly zero in the Born approximation. The ex...

Zusammenfassung:We report the first measurement of the target single-spin asymmetry in deep-inelastic scattering from the inclusive reaction 3He↑(e,e')X on a 3He gas target polarized normal to the lepton plane. Assuming time-reversal invariance, this asymmetry is strictly zero in the Born approximation. The experiment, conducted at Jefferson Lab using a 5.89 GeV electron beam, covers a range of 1.7
