Accelerating Atomic Fine Structure Determination with Graph Reinforcement Learning
M. Ding, V. -A. Darvariu, A. N. Ryabtsev +2
Atomic data determined by analysis of observed atomic spectra are essential for plasma diagnostics. For each low-ionisation open d- and f-subshell atomic species, around fin…

Laboratory confirmation and improved Accuracy of 4f and 5d energy levels of Fe II previously identified from stellar spectra
M. Ding, H. Kozuki, F. Concepcion +2
Many energy levels of singly ionised iron (Fe II, ) remain uncertain or experimentally unknown. Their identification and spectral line data are required in reliable astrophys…

Spectrum and energy levels of the high-lying singly excited configurations of Nd III
M. Ding, A. N. Ryabtsev, E. Y. Kononov +2
Fourier transform spectra of Nd Penning and hollow cathode discharge lamps were recorded within the region 32,500-54,000 cm (3077-1852 Å) and grating spectra of Nd vacuum sl…
