Description
Nuclear level densities (NLDs) are fundamental for describing statistical properties of atomic nuclei and play a central role in nuclear structure and reaction studies as well as in nucleosynthesis calculations.
In this work, we present the determination of the NLDs for the even tin isotopes $^{116,118,120}$Sn. High-resolution nuclear spectra from $(d,p\gamma)$ reactions, measured with the SONIC@HORUS setup at the 10-MV FN Tandem accelerator at the University of Cologne, were analyzed using the fluctuation analysis technique. This approach enables a direct extraction of the densities for $1^{-}$ states without relying on assumptions about spin distributions and hence providing a model-independent determination of the underlying NLD. The experimental data are compared to theoretical models including spin distributions.
