A theory for computing cross sections for inclusive A(d,p)X processes has been previously developed [1]. This includes direct neutron transfer to bound states, transfer to the continuum, as well as inelastic processes. Therein, local optical potentials are used to describe the nucleon-target interaction. We extend this framework to investigate the effects of nonlocality in the optical potentials for A(d,p)X reactions populating neutron bound and scattering states. We obtained neutron wave functions for nonlocal interactions of the Perey-Buck type within the R-matrix method [2]. Here, I will discuss the A(d,p)X processes on 16O, 40Ca, 48Ca and 208Pb at 10, 20 and 50 MeV.
