title: Vibronic and spin-orbit coupling of a d9 transition-metal ion encapsulated in an icosahedral cage: the (Gamma8+Gamma9)x(g+2h) Jahn-Teller problem.
abstract: Interplay between the vibronic and spin-orbit coupling in the (Gamma8+Gamma9)x(g+2h) Jahn-Teller problem, where Gamma8 and Gamma9 are the quartet and sextet spin representation, and g and h denote the fourfold and fivefold degenerate vibrational modes in icosahedral symmetry, respectively, is studied. A 4d9 or 5d9 transition-metal ion in an icosahedral field may provide a realization of this system.
