A CSFG-based neural network basis-selection method for large-scale RCI calculations within GRASPG
Chaofan Shi, Shaowei Tian, Ran Si +3
We present a neural network (NN) basis-selection method for large-scale relativistic configuration interaction (RCI) calculations in GRASPG. The method employs configuration state…
Non-orthogonal extension of Graspg - dynamic electron correlation for large and compact active spaces
Sijie Wu, Ran Si, Chongyang Chen +3
Accurate relativistic multiconfiguration calculations of correlation-sensitive atomic properties are often limited by the rapid growth of configuration state function expansions wh…
Extended atomic data for oxygen abundance analyses
W. Li, P. Jönsson, A. M. Amarsi +2
As the most abundant element in the universe after hydrogen and helium, oxygen plays a key role in planetary, stellar, and galactic astrophysics. Its abundance is especially influe…
Benchmarking calculations with spectroscopic accuracy of level energies and wavelengths in W LVII - W LXII tungsten ions
Chun Yu Zhang, Kai Wang, Ran Si +5
Atomic properties of states of the W W ions are systematically investigated through two state-of-the-art methods, namely, the second-order many-body pertu…
Extended theoretical transition data in C I - IV
W. Li, A. M. Amarsi, A. Papoulia +2
Accurate atomic data are essential for opacity calculations and for abundance analyses of the Sun and other stars. The aim of this work is to provide accurate and extensive results…
Extended calculations of energy levels, radiative properties, , hyperfine interaction constants, and Landé -factors for nitrogen-like \mbox{Ge XXVI}
K. Wang, C. Y. Zhang, P. Jönsson +6
Employing two state-of-the-art methods, multiconfiguration Dirac--Hartree--Fock and second-order many-body perturbation theory, highly accurate calculations are performed for the l…
