摘要：

The Ajiki-Ando (A-A) splitting of single-walled carbon nanotubes (SWNTs) originating from the Aharanov-Bohm effect was observed in chiral-specific SWNTs by the magneto-absorption measurements conducted at magnetic fields of up to 78 T. The absorption spectra from each chirality showed clear A-A splitting of the E-11 optical excitonic transitions. The parameters of both the dark-bright exciton energy splitting and the rate of A-A splitting in a magnetic field were determined for the first time from the well-resolved absorption spectra.
