Abstract
We perform a classical dynamics study of the proton transfer reactions measured for the $^{12}\mathrm{C}$${+}^{197}$Au and $^{16}\mathrm{O}$${+}^{197}$Au systems. The nuclei are assumed to move along classical trajectories, and the proton transfer probability is considered as a tunneling process around the point of closest approach. The absorption due to the imaginary part of the optical potential also is included. At the highest energies considered, several trajectories contribute to each scattering angle. The contributions associated to the different trajectories are added to obtain the proton transfer probability. We find that, for a properly selected value of the strength parameter in the imaginary part of the optical potential, the theoretical results fit adequately the experimentally measured values. \textcopyright{} 1996 The American Physical Society.
