Detailed measurements of the angular distribution for the "C+' C~' C+' C single neutron transfer reaction as a function of bombarding energy from just above the Coulomb barrier to approximately four times the barrier energy are reported. The distorted-wave Born approximation for the transfer process does not reproduce the strong oscillations observed in both the experimental angular distributions and excitation functions, while analyses using a two-pole model for the transfer amplitude indicate significant multistep contributions. We show that the cross section in the 96 region in the center of mass is characteristic of an increased collision delay time and of an effective Q value l MeV smaller than the asymptotic observable Q value. Angular distributions calculated using the dynamic two-center shell model of Konnecke et al. also succeed in reproducing the salient features of the data. The present experiment provides evidence for the occurrence of single-particle nuclear molecular behavior in a heavy-ion neutron transfer reaction. Data for the elastic scattering of ' C+ ' C are also presented and analyzed. We conclude that the elastic scattering excitation functions are consistent with the occurrence of orbiting in the dynamic interaction.
