Near-infrared photoabsorption by C60 dianions in a storage ring.
We present a detailed study of the electronic structure and the stability of C(60) dianions in the gas phase. Monoanions were extracted from a plasma source and converted to dianions by electron transfer in a Na vapor cell. The dianions were then stored in an electrostatic ring, and their near-infrared absorption spectrum was measured by observation of laser induced electron detachment. From th...
متن کاملTopological effects on magnitude of persistent current in a ring
We show that defects in 1D rings decrease the conductance (when the ring is opened up) many more times than it decreases the persistent currents. This means that the states in such a 1D ring are very sensitive to twisting of boundary condition but conductance of the system is small. In 1D the electron effectively sees a periodic potential and escapes localization. This does not happen in higher...
متن کاملNonresonant Raman spectrum of C60 nanopeapod: C60 polymerization effects
We present a force constants model for the vibrational modes in C60 dimer and polymer phases. The results of this model are used to calculate the nonresonant Raman spectra of infinitely long isolated C60 dimer and polymer peapod in the framework of bondpolarization theory by using the spectral moment’s method. The changes of the Raman spectrum in terms of the structure of the C60 molecules insi...
متن کاملThe effects of dynamic ionospheric outflow on the ring current
[1] The importance of ionospheric O on the development of the storm time ring current is recognized but not well understood. The addition of this outflow in global MHD models has the potential to change the magnetic field configuration, particle densities and temperatures, and the convection electric field. This makes including heavy ion outflow in ring current simulations difficult, as this ad...
متن کاملPersistent spin current in anisotropic spin ring
The persistent spin current in an anisotropic spin ring penetrated by a SU(2) flux is studied by the Schwinger–Boson mean-field approach. The anisotropy in spin coupling can facilitate the persistent spin current. Ground-state energy and excitation-energy gap are also studied. A peak of spin current occurs at the maximum value of the ground-state energy. r 2006 Published by Elsevier B.V. PACS: ...
