Investigations of the deuteron break-up on heavy nuclei above the Coulomb barrier

The deuteron break-up on heavy nuclei is studied for deuteron energies above the Coulomb barrier in the post form of the DWBA. The “region of formation” of the DWBA integral is found to be located mainly outside the nuclear force range. Finite-range, non-locality and virtual break-up effects are carefully considered. A comparison of our theoretical calculations with the available experimental coincidence cross sections shows good agreement. This supports strongly the validity of the direct break-up model assumed here.
