Groenenboom. 2005. “Polarizabilities of Sc and Ti Atoms and Dispersion Coefficients for Their Interaction with Helium Atoms.” Physical Review A 72 (3) (September 7). doi:10.1103/physreva.72.032703.1050-2947http://nrs.harvard.edu/urn-3:HUL.InstRepos:30403729The dynamic scalar and tensor polarizabilities of Sc and Ti are computed with time-dependent density functional theory. These polarizabilities are used to compute the isotropic and anisotropic dispersion interactions in ScHe and TiHe. We find C6,0(ScHe)=30.00 , C6,2(ScHe)=-1.63 , C6,0(TiHe)=28.40 , and C6,2(TiHe)=-0.90 (Eha06) . We show that an estimate of the dispersion anisotropy based on static polarizabilities results in an overestimation by a factor of 2.en-USJournal Article2017-02-2110.1103/PhysRevA.72.032703
