CALCULATION OF OPTICAL POLARIZABILITY OF ATOMS WITH TWO OPEN SHELLS IN THE HARTREE-FOCK APPROXIMATION

Time-dependent Hartree-Fock equations (the Huzinaga method) in terms of density functionals have been obtained for a multielectronic system with two open shells of different symmetry species subjected to a time-dependent external perturbation. Based on these, the equations of time-dependent "bound" perturbation theory have been written in the orbital representation. The dynamic dipole polarizability of a number of atoms with two open shells with s(1)p(n)-configurations has been calculated using an optimized basis set of Slater-type atomic orbitals.
