pairs. The philosophy behind this approach is based on the hypothesis that the chiral symmetry breaking and confinement are relatively independent mechanisms and they can be investigated separately \[\].

Second, the self-consistent solitonic solution ([*hedgehog*]{}) has been found to exist in the large $N_c$ limit of the model within the physically acceptable range of parameters \[\]. The chiral soliton provides a good description of the nucleon and gives us possibility to take into account vacuum polarization effects from the Dirac quark sea. Calculations done in the semiclassical quantization procedure yield quite reasonable results for the vacuum and nucleon sectors \[-\]. In particular, quantities like the nucleon radii, $\Sigma$–terms, axial vector coupling constant, $\Delta$–nucleon splitting, splittings within the octet and decuplet are well reproduced.

Third, there are various hints that the NJL-type Lagrangian can be obtained \[,,,\] as a long wavelength limit of QCD. It should be stressed that the large $N_c$ limit plays a prominent role in those considerations.

The aim of this paper is to compute the electromagnetic nucleon form factors within the $SU(2)$ chiral quark soliton model based on the semibosonized NJL-type lagrangean with the vacuum polarization effects taken into account. The calculations will include the rotational $1/N_c$
