Fusion and transfer in at near barrier energies

Abstract

Energy-integrated one- and two-proton transfer cross sections and fusion excitation functions have been measured for and at energies near the Coulomb barrier. As in previous results with projectiles, anomalous dependence of the transfer probability on distance of closest approach is observed at energies only slightly above the barrier. Measured fusion cross sections show sub-barrier enhancement similar to that measured in other systems. Coupled-channel calculations including transfer form factors extracted from the measurements come closer to the data in the measurements and produce the full enhancement for .
