In transport measurements we observe three stable series of Fano resonances with similar lineshapes. We present a simple model explaining the temperature and V_{SD} dependence of the resonances. The Fano regime allows to investigate phase and coherence of the electronic wave function and astonishingly, we find no signs of decoherence in our system.4 pages, 4 figuresMesoscale and Nanoscale Physicstext
