Scientific paper

A new diagrammatic method, which is a reformulation of Berezinskii's technique, is constructed to study the density of electronic states $\rho(\epsilon,\phi)$ of a one-channel weakly disordered ring, threaded by an external magnetic flux. The exact result obtained for the density of states shows an oscillation of $\rho(\epsilon,\phi)$ with a period of the flux quantum $\phi_0= hc/e $. As the sample length (or the impurity concentration) is reduced, a transition takes place from the weak localization regime (L >> l) to the ballistic one (L <= l). The analytical expression for the density of states shows the exact dependence of $\rho(\epsilon,\phi)$ on the ring's circumference and on disorder strength for both regimes.
