  1. N. Nikolov, N. Schunck, W. Nazarewicz, M. Bender Large Deformation Data in DFT Fits Proposal: Include data on well-deformed nuclei like position of bandheads of super-deformed bands or fission isomers in the fit of the functional • Leptodermous expansion: LDM Energy from microscopic effective interactions • Observation: some parameters of the expansion (assym) are very poorly constrained Isospin and mass dependence imply larger uncertainties in neutron-rich nuclei

  2. N. Nikolov, N. Schunck, W. Nazarewicz, M. Bender • Leptodermous expansion show stability of deformed neutron-rich nuclei caused by (poorly constrained) surface-symmetry energy • Benchmarking of excitation energy of super-deformed states and fission isomers with microscopic interactions show fluctuations larger than theoretical and experimental uncertainties [1] P.-G.
