The relative branching ratio B(D0 -> K+pi-)/B(D0 -> K-pi+) is measured to be (1.84+-0.59(stat.)+-0.34(syst.))%. The two possible contributions to the D0 -> K+pi- decay, doubly cabibbo-suppressed decays and D0-Dbar0 mixing, are disentangled by measuring the proper-time ditribution of the reconstructed D0's. Assuming no interference between the two processes, the upper limit obtained on the mixing rate is 0.92% at 95% CL.
