Relativistic coupled-cluster calculations of the energies, Lande g factors, radiative transition properties including line strengths, oscillator strengths, and transition rates for Th 3+

Energies, Lande g factors, line strengths, transition probabilities, and oscillator strengths for electric dipole (E1), electric quadrupole (E2), and magnetic dipole (M1) transitions arising from the nS 1 / 2 ( n = 7-10), nP 1 / 2 , 3 / 2 ( n = 7-9), nD 3 / 2 , 5 / 2 ( n = 6-9), nF 5 / 2 , 7 / 2 ( n = 5-8), and nG 7 / 2 , 9 / 2 ( n = 5,6) energy levels in Th 3+ , 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 Th 3+ and is of great significance for future spectral analysis and precision experiments targeting various applications.
