An analysis is made of the angular distribution and polarization of 185-Mev protons inelastically scattered by carbon. A rough calculation using the distorted wave Born approximation shows, even though the quantitative agreement is poor, that the 4.4-Mev level of ${\mathrm{C}}^{12}$ may be interpreted as a collective state.
