title = "Multipole excitations of two joint conducting spheres: Application to C119 molecule",
abstract = "Model of coupled spherical shell quantum wells is applied to C119 molecule. In a frame of the model the frequencies of the collective excitation series are calculated. The lowermost excitation, which could be detected by optical methods, is founded to have essentially dipolar character. Two types of the coupled oscillations exist with a different parity, which frequencies shifted up and down from C60 molecule plasmon frequency. For a dipole mode the two plasmon peaks with a gap about 3.5 eV have different dipole polarization. A transition to the usual coupled plasmons in two metal planes is fulfilled.",

note = "Funding Information: In summary, we developed coupled spherical quail-tum well approach to calculate high frequency respouse of Cirs molecule. There is a splitting of frequency of composed plasmon of Cris of the order of the mull,i- pole Coulomb interaction between two spheres. We find Ciis to have a lowermost excitation series ceutred a,1 CIss molecule plasmon frequency. This series corresponds Co in-phase (dipole) and contra-phase (quadrupole) oscilla- tions of the electron density of both globes and consists of z-and x-, y-polarizations relatively to molecule axis. According to our estimation, there is a splitting of 3.5 eV between two dipole plasmon pikes of Girs molecule. Oscillator strength for lower pike is twice higher than for upper pike. We show that our result for two joined SSQWs reproduces 2DEG plasma behaviour in the limit of infinitely large sphere. Acknowledgments.
