Abstract. The dipole dynamic polarizability of Zn atom is calculated within the framework of the Hartree-Fock method (HF) and by taking into account the correlations in the random phase with exchange (RPAE) approximation. The importance of taking into account the many-electron correlations, especially for heavier atoms, are pointed here.

DIPOLNA DINAMIČKA POLARIZABILNOST CINKA U radu je računata dipolna dinamička polarizabilnost atoma cinka primenom Hartrre-Fockovog metoda sa uzimanjem u obzir korelacija primenom aproksimacije slučajnih faza sa izmenom. Posebna pažnja se poklanja pokazivanju da je za teže atome veoma bitno uzimanje u obzir višeelektronskih korelacija.
