  A current interest in nuclear reactions, specifically with rare isotopes
concentrates on their reaction with neutrons, in particular neutron capture. In
order to facilitate reactions with neutrons one must use indirect methods using
deuterons as beam or target of choice. For adding neutrons, the most common
reaction is the (d,p) reaction, in which the deuteron breaks up and the neutron
is captured by the nucleus. Those (d,p) reactions may be viewed as a three-body
problem in a many-body context. This contribution reports on a feasibility
study for describing phenomenological nucleon-nucleus optical potentials in
momentum space in a separable form, so that they may be used for Faddeev
calculations of (d,p) reactions.
