Precise results on the spin-dependent structure functions g{sub 1}{sup p}(x,Q{sup 2}) and g{sub 1}{sup d}(x,Q{sup 2}) over the kinematic range 0.0021 < x < 0.9 and 0.1 < Q2 < 20 GeV2 are presented. The analyses base on data collected at the HERMES experiment at DESY in polarized deep-inelastic scattering and make use of an unfolding algorithm in order to correct for radiation and detector smearing. Furthermore, final results of the first measurement of the tensor asymmetry Azz and the tensor structure function b{sub 1}{sup d}(x,Q{sup 2}) are provided.
