The spin program with CLAS at JLab
- 15 Downloads
We report on the status of an extensive program to study the scattering of longitudinally polarized electrons from longitudinally polarized NH3 and ND3 targets using the CLAS detector at JLab. The data span a range inQ 2 from 0.05–4.5 (GeV/c)2 and a range inW, the γ* N invariant mass, up to about 3 GeV. With the excellent particle identification available with the CLA, both inclusive and exclusive scattering can be studied. The experimental techniques are reviewed and some preliminary results are presented. This paper focuses on extraction of the spin structure functiongg 1 for the proton and the deuteron.
