Leptodermous expansion: LDM Energy from microscopic effective interactions
Observation: some parameters of the expansion (assym) are very poorly constrained

Proposal: Include data on well-deformed nuclei like position of bandheads of super-deformed bands or fission isomers in the fit of the functional
Isospin and mass dependence imply larger uncertainties in neutron-rich nuclei

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
