@proceedings{oai:nifs-repository.repo.nii.ac.jp:02000516, month = {May}, note = {ORCID 0000-0002-5302-073X, New calculations of atomic structures for r-process elements in ejecta of binary neutron star coalescence have been conducted using HULLAC and GRASP2K codes. The results are compared and used to evaluate impact of accuracy in the atomic calculations to opacities of electromagnetic emission from the ejecta. Universality and physical properties in complex open f-shell energy level structures of Nd II and Er II are investigated by coarse-graining methods. The energy level structures are well characterized in terms of statistics of the skewed normal distributions.}, publisher = {National Institute for Fusion Science}, title = {Statistical properties of atomic structures of r-process elements}, volume = {114}, year = {2019} }
