Spin asymmetries A 1 and structure functions g 1 of the proton and the deuteron from polarized high energy muon scattering

We present the final results of the spin asymmetries A 1 and the spin structure functions g 1 of the proton and the deuteron in the kinematic range 0.0008<x<0.7 and 0.2<Q 2 <100 GeV 2 . For the determination of A 1 , in addition to the usual method which employs inclusive...
