  The breakup cross section (BUX) of 22C by 12C at 250 MeV/nucleon is evaluated
by the continuum-discretized coupled-channels method incorporating the
cluster-orbital shell model (COSM) wave functions. Contributions of the
low-lying 0+_2 and 2+_1 resonances predicted by COSM to the BUX are
investigated. The 2+_1 resonance gives a narrow peak in the BUX, as in usual
resonant reactions, whereas the 0+_2 resonant cross section has a peculiar
shape due to the coupling to the nonresonant continuum, i.e., the Fano effect.
By changing the scattering angle of 22C after the breakup, a variety of shapes
of the 0+_2 resonant cross sections is obtained. Mechanism of the appearance of
the sizable Fano effect in the breakup of 22C is discussed.
