Pauli principle and single particle state fragmentation in odd spherical nuclei with A approximately 55

In the framework of a nucleus quasiparticle-phonon model equations for odd nuclei with successive account of the Pauli principle are obtained. It is shown that the Pauli principle precise account effect on the single quasi particle states fragmentation at medium and high excitation energies is not important and in most cases one can limit itself by the Pauli principle approximate account
