Structure in the Excitation Functions ofC12(O16,p)Al27,C12(O16,d)Al26, andC12(O16,α)Mg24

The excitation functions for the above reactions show evidence for a large statistical conpound-nucleus contribution. In addition, a broad structure (∼1 to 2 MeV) is seen in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^{16}{}_{}{}^{}\mathrm{O},\alpha ){}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$, and narrower correlated resonances (∼300 keV) appear in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^{16}{}_{}{}^{}\mathrm{O},p){}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$, one of them, at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}=19.71\mathrm{}$ MeV, having the same position and width as a recently found anomaly in ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$+ ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ elastic and inelastic scattering.
