Complete and incomplete fusion and emission of preequilibrium nucleons in the interaction of ¹²C with ¹⁹⁷Au below 10 MeV/nucleon

The excitation functions for production of nineteen isotopes of At, Po, Bi, Pb, and Tl in the interaction of ¹²C with ¹⁹⁷Au between 57 and 97 MeV incident energy have been measured with the activation technique. The analysis of these data allows one to estimate the cross sections for complete fusion of ¹²C and incomplete fusion of ⁸Be and α fragments with gold, and shows the presence of preequilibrium emissions at incident energies only slightly higher than the Coulomb barrier acting between ¹²C and ¹⁹⁷Au.
