Reducing Ambiguities in Spectroscopic Factors with Combined Measurements and the $^{86}$Kr(d,p) Reaction at 35MeV/u

Spectroscopic information for low-lying states above shell closures depends on the shape of the bound-state potential, which greatly affects the extracted spectroscopic factors. To mitigate this uncertainty, Mukhamedzhanov and Nunes [1] have proposed a combined method; the external portion is fixed with a peripheral reaction, and is combined with a higher energy measurement with a larger contribution from the interior. This will constrain the single-particle ANC, and should enable spectroscopic factors to be deduced with uncertainties dominated by cross-section measurements rather than the bound-state potential. Published measurements of $^{86}$Kr(d,p) at 5.5MeV/u [2] were used for the external contribution of this reaction. An ANC analysis shows that the reaction is peripheral at this energy and the ANC has been extracted. At less-peripheral energies, $^{86}$Kr(d,p) at 35MeV/u has been measured in inverse kinematics at the NSCL using the ORRUBA and SIDAR arrays of silicon strip detectors. Results of the ANC analysis and preliminary results from $^{86}$Kr(d,p) at 35MeV/u will be presented. This work is supported in part by the NSF and the U.S. DOE.
