Fano Resonances are a new continuum excitation mode in light exotic nuclei. By the QPC model we explain these sharp and asymmetric structures as due to the coupling of a single particle elastic channel to the closed core-excited channels. Theoretical model calculations are compared for 15C, 17C and 19C. The theoretical results for 15C are in qualitative agreement with the experimental spectrum.
