The LO BK equation for unintegrated gluon density with impact parameter dependence is considered. The form of initial condition for the equation is determined, which is similar to the form of fenomenological GBW ansatz. The gluon density function and F2 function are calculated and compared with the results for the gluon density and F2 functions from the GRV parameterization for different values of Q 2. It is shown, that the results for F2 structure function of the considered model are in the good accordance with the results obtained from the GRV parameterization of parton densities. Therefore, obtained initial conditions for unintegrated gluon density could be used for the calculation of proton–proton scattering process as well, S. Bondarenko, L. Motyka, in preparation.
