Resumo
Fifteen strongly oscillating angular distributions of the elastic scattering of C12+Mg24 at energies around the Coulomb barrier (Ec.m.=10.67-16.00MeV) are reproduced by adding five Breit-Wigner resonance terms to the l=2,4,6,7, and 8 elastic S matrix. The nonresonant, background elastic scattering S matrix Sl0 is calculated using the São Paulo potential. The J=2,4,6,7, and 8 molecular resonances fit well into a rotational molecular band, together with other higher lying resonances observed in the O16+Ne20 elastic scattering. We propose that the presently observed, largely deformed molecular band corresponds to the hyperdeformed band, which has been found previously in α-cluster calculations, as well as in a new Nilsson model calculation. Systematic study of its possible clusterizations predicts the preference of the C12+Mg24 and O16+Ne20 molecular structure, in accordance with our present results. © 2009 The American Physical Society.
