Characterization of gross-structure resonances in angular-momentum-mismatched channels in heavy-ion collisions

Gross-structure resonances previously observed only in inclusive measurements have been studied in both single and mutual inelastic scattering involving the $0_2^{+}$ state of ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$. Analysis of the excitation functions in the single-excitation channel at the zeros of Legendre polynomials permits the dominant L values to be determined for most of the resonances. The measured spins disagree with the predictions of a recently published microscopic model of the inelastic-scattering process.
