We have observed a strong peak in the excitation function for the inelastic scattering reaction {sup 12}C({sup 12}C,{sup 12}C(0{sub 2}{sup +})){sup 12}C(0{sub 2}{sup +}) at an energy of {ital E}{sub c.m.}=32.5 MeV. A recoil coincidence arrangement between two double-sided silicon strip detectors was used to detect the {alpha} particles from the decaying {sup 12}C nuclei, and the reconstructed reaction kinematics were used to calculate the two-body scattering {ital Q} value. This excitation-function structure may be interpreted as arising from very highly deformed {alpha}-particle chain configurations in the nucleus {sup 24}Mg.
