We measured the differential cross sections for the 0{sub 2}{sup +} state at E{sub x} = 7.654 MeV in {sup 12}C via the (p,p') reaction at an incident energy of 300 MeV, and in an angular range from 2.7 deg. to 40 deg. We analyzed the data with the distorted-wave Born-approximation (DWBA) employing transition densities obtained in a macroscopic collective model, a microscopic alpha-cluster model, and a microscopic alpha-cluster condensation model. It is concluded that the present results for the {sup 12}C(p,p') reaction at 300 MeV is quite consistent with the assumption that the 0{sub 2}{sup +} state at E{sub x} = 7.654 MeV has the wave function with the alpha-cluster condensation.
