中文摘要	the energy spectrum and the persistent currents are calculated for a finite-width mesoscopic annulus with radial potential barrier, threading a magnetic flux through the hole of the ring. owing to the presence of tunneling barrier, the coupling effect leads to the splitting of each radial energy subband of individual concentrical rings into two one. thus, total currents and currents carried by single high-lying eigenstate as a function of magnetic flux exhibit complicated patterns. however, periodicity and antisymmetry of current curves in the flux still preserve.
