B. Adeva et al., Spin asymmetries A(1) and structure functions g(1) of the proton and the deuteron from polarized high energy muon scattering - art. no. 112001, PHYS REV D, 5811(11), 1998, pp. 2001
We present the final results of the spin asymmetries A(1) and the spin stru
cture functions g(1) of the proton and the deuteron in the kinematic range
0.0008 < x < 0.7 and 0.2 < Q(2) < 100 GeV2. For the determination of A(1),
in addition to the usual method which employs inclusive scattering events a
nd includes a large radiative background at low x, we use a new method whic
h minimizes the radiative background by selecting events with at least one
hadron as well as a muon in the final state. We find that this hadron metho
d gives smaller errors for x < 0.02, so it is combined with the usual metho
d to provide the optimal set of results. [S0556-2821(98)07017-9].
