Anisotropic dipole polarizability of transition metal atoms: Sc(D-2), Ti(F-3,P-3), V(F-4,P-4,D-6), Ni(F-3) and ions: Sc2+(D-2), Ti2+(F-3,P-3) - art. no. 024308

摘要

Dipole polarizability tensor components and quadrupole moments of transition-metal atoms Sc, Ti, V, Ni, and Cu and ions Sc2+ and Ti2+ are computed using finite field complete active space self-consistent field and multireference configuration interaction ab initio methods. Perpendicular components of the dipole polarizability tensor are calculated from equations involving only parallel components of the polarizability tensor and its average value. Mean polarizability and polarizability anisotropy decrease in the Sc-Ni series. Relativistic effects are accounted for with the Douglas-Kroll Hamiltonian. The consequences of the anisotropic properties of these atoms to their interactions with spherically symmetric rare gases are also discussed. (c) 2005 American Institute of Physics.
