Single particle transfer reactions have been used extensively to explore the structure of exotic, neutron-rich nuclei; however, these reactions are typically measured at energies where only a peripheral reaction can occur, without probing the interior of the nuclear wave function. At low energies (~5 MeV/u), the single neutron strengths cannot be reliably extracted without a detailed description of the bound-state potential. Mukhamedzhanov and Nunes  have proposed a method to constrain the shape of the bound state potential by combining transfer reaction measurements at two different energies. The 86Kr(d,p)87Kr reaction has been used as a test case for this method. 86Kr(d,p) at 35 MeV/u has been measured in inverse kinematics at the NSCL using the ORRUBA and SIDAR arrays of silicon strip detectors and is combined with previous measurements at 5.5 MeV/u. Preliminary analysis shows that the single-particle ANC can be constrained. The details of the analysis and prospects for measurements with neutron-rich beams will be presented.
