Three-body direct nuclear reactions: Nonlocal optical potential

The calculations of three-body direct nuclear reactions with nonlocal optical potentials are performed for the first time using the framework of Faddeev-type scattering equations. An important nonlocality effect is found for transfer reactions such as $d+{}^{16}\mathrm{O}\to p+{}^{17}\mathrm{O}$, often improving the description of the experimental data.
