| contents | The nonelastic breakup (NEB), one of channels in $(d,p)$ inclusive reactions, is studied using the Faddeev-type scattering theory. The NEB differential cross section is obtained in terms of the imaginary part of the neutron-nucleus optical potential sandwiched between the Alt-Grassberger-Sandhas three-body transition operators. The momentum-space calculations including the Coulomb force are extended to higher charge numbers. Well converged numerical results are obtained for the energy distribution of the NEB cross section, being roughly consistent with previous works. The spin-dependent interaction terms do not play a significant role. The optical potential nonlocality effect shows up at higher proton energies, but is comparable to local potential uncertainties. |
