We searched for the 6-condensed state in Mg by measuring the C+C scattering with the SAKRA Si detector array. By using the invariant-mass method for the detected 3 particles, the inclusive cross sections for the C+C C(0) + X and C(3) + X reactions were determined. In both the inclusive C(0) + X channel and the exclusive C(0) + C(0) channel, the cross section peaked at E = 19.4 MeV, which correspond to the excitation energy of E = 33.3 MeV in Mg. This 19.4-MeV state is a candidate for the 6-condensed state
