Resumen:
In the present article we perform analytical and numerical calculations related to persistent current in 2D isolated mesoscopic annular cavities trheaded by a magnetic flux. The system considered has a high number of open channels and therefore the single particle spectrum exhibits many levels crossings as the flux varies. We determine the effect of thedistribution of level crossings in the typical persistent current.
