Relativistic coupled-cluster calculations of the energies, Landé g factors, radiative transition properties including line strengths, oscillator strengths, and transition rates for Th3+

Abstract

Energies, Landé g factors, line strengths, transition probabilities, and oscillator strengths for electric dipole (E1), electric quadrupole (E2), and magnetic dipole (M1) transitions arising from the nS1/2 (n=7-10), nP1/2,3/2 (n=7-9), nD3/2,5/2 (n=6-9), nF5/2,7/2 (n=5-8), and nG7/2,9/2 (n=5,6) energy levels in Th3+, are calculated using the singles and doubles approximation of the relativistic coupled-cluster (CCSD) method. The data are compared with available experimental and theoretical results, showing a good agreement. To the best of our knowledge, many results are reported for the first time. This work reports a high-precision atomic property calculation of Th3+ and is of great significance for future spectral analysis and precision experiments targeting various applications.
