Analysis of direct and indirect processes of two-proton-transfer reactions performed on Ni64 and Mo100

The Ni64(O16, C14)Zn66 and Mo100(C12, Be10)Ru102 angular distributions have been measured between 13°and 70°(lab), respectively, at 56 and 48 MeV incident energies. Distorted-wave Born approximation and coupled-channel Born approximation analyses have been performed using exact finite range codes. The marked difference in the angular distributions between the Ru102 ground state and 2+ state can be well described using coupled-channel Born approximation calculations that take into account the important indirect processes. Furthermore, the relative intensities among various states are better reproduced by coupled-channel Born approximation calculations than by distorted-wave Born approximation calculations.
