Abstract

We propose a unified approach which describes both structure functions in the small-x region and diffractive production in γ^*p-interactions. It is shown that the model, based on reggeon calculus and a quark-parton picture of the interaction, gives a good description of available experimental data in a broad region of Q² (including Q² =0) with a single Pomeron of intercept α_P(0) = 1.2. Predictions for very small x are given and the problem of saturation of parton densities is discussed.
