About Q2 Dependence of the Measured Asymmetry A_1(x)

We propose the new approach for taking into account the Q2 dependence of measured asymmetry A_1. This approach is based on the similarity of the Q2 behaviour and the shape of the spin-dependent structure function g_1(x,Q^2) and spin averaged structure function F_3(x,Q^2). The analysis is applied on the SMC and E154 experimental data.
