Model-independent determination of nuclear properties provides essential benchmarks for both statistical observables, and the assumptions underlying several experimental methods. Such approaches are central to constraining quantities relevant for stellar nucleosynthesis [1] and nuclear structure phenomena [2].

This contribution presents a set of continuum and state-to-state methods applied to the tin isotopes ^116,118,120Sn, especially the ^A−1Sn(d,pγ )^ASn reactions as seen in [3], to extract information in a consistent manner. The combination of selective electromagnetic [4] and hadronic probes and modern analysis techniques [5] enables direct determination of nuclear structure properties, like nuclear level densities (NLDs).
