| Abstract: | We present parametrizations for the proton structure functionF 2 in the next to leading order in perturbative QCD. We consider that the dominant term toF 2(x, Q 2) should grow asx ?ψ s for smallx values, with the exponentλ S being essentially independent ofQ 2. Comparisons with the most recent H1 and ZEUS data confirm the valueλ S ～0.35 obtained previously from fits to low energy data. |
