Hermes Precision Results on g{1}{p}, g{1}{d} and g{1}{n} and the First Measurement of the Tensor Structure Function b{1}{d}

Final HERMES results on the proton, deuteron and neutron structure function g₁ are presented in the kinematic range 0.0021 < x < 0.9 and 0.1 < Q² < 20 GeV². These results are based on a refined analysis and are corrected for radiative and detector smearing effects using an unfolding algorithm. Furthermore, preliminary results on the first measurement of the tensor asymmetry A_zz and the tensor structure function b_{1}^{d} are presented.
