Anisotropic dipole polarizabilities and quadrupole moments of open-shell atoms and ions: O, F, S, Cl, Se, Br and isoelectronic systems

Quadrupole moment and dipole polarizability tensor components are calculated at the correlated complete-active-space self-consistent-field (CASSCF) and complete-active-space perturbation-theory (CASPT) levels for P-2 states of O-, F, Ne+, Na2+, S-, Cl, Ar+, K2+, Se-, Br, Kr+, Rb2+ and P-3, D-1, S-1 states of O, F+, Ne2+, Na3+, S, Cl+, Ar2+, K3+, Se, Br+, Kr2+ Rb3+. Relativistic corrections are included perturbatively for the 34- and 35-electron systems.
