The Q2 dependence of the measured asymmetry A1 from the similarity of   g1(x,Q2) and F3(x,Q2) structure functions
  We propose a new approach for taking into account the Q^2 dependence of measured asymmetry A1. This approach is based on the similarity of the Q2 behaviour and the shape of the spin-dependent structure function g1(x,Q^2) and spin averaged structure function F3(x,Q^2). The analysis is applied on available experimental data.
