Title: Multipole plasmon excitations of C{sub 60} dimers

We study the multipole plasmon mode frequencies of a pair of C{sub 60} molecules by means of the linearized hydrodynamic theory for electronic excitations on the each C{sub 60} surface. We apply the two-center spherical coordinate system for mathematical convenience and find an explicit form of the surface plasmon energies. Numerical result shows when approaching the two C{sub 60} molecules, the coupling between the bare plasmon modes leads to the appearance of additional modes having energies that are different from those of the isolated C{sub 60} molecules.
