We aim to present first large scale and systematic investigation on atomic properties of Ge-like ions: As1+, Se2+, Br3+, and Kr4+. The multiconfiguration Dirac–Hartree–Fock and relativistic configuration interaction methods, which are implemented in the general-purpose relativistic atomic structure package Grasp2018, are used in the present work. We computed the energy levels of the 4s2 4p2, 4s4p3, 4p4, 4s2 4p {5s, 6s, 5p, 6p, 4d, 5d, 4f}, and 4s4p2 {4d, 5s} configurations and the electric dipole, magnetic dipole, and electric quadrupole transitions between states of these configurations. The accuracy of energy levels is evaluated by comparing our results with the recommended values of the National Institute of Standards and Technology Atomic Spectra Database and with energy levels estimated with various methods. The accuracy of transition data is investigated using the quantitative and qualitative evaluation method. We applied our results to astrophysics by constructing the list of M1-type transitions for kilonova. For Ge-like ions presented in this paper, we confirmed that the transition list assuming the LS-coupling selection rules, as adopted in the previous studies, includes all the important transitions and that an analytical formula for transition probabilities gives a good accuracy.

The energy levels, transition probabilities, oscillator strengths, line strengths and wavelengths of Ge-like Zr, Nb and Tc ions have been calculated using the multiconfiguration Dirac-Hartree-Fock method. The Breit interactions and quantum electrodynamics correction were taken into account. The calculated values of energy levels and wavelengths have been compared with other theoretical calculations and available experimental values, good agreements are achieved for most of the energy levels and wavelengths calculated. The number of energy levels and wavelengths considered is larger than that of any other theoretical calculations. And the transition probabilities, line strengths are also given where no other theoretical results and experimental values are available.

The present work reports results of spectral parameters of Zn-like, Ga-like, and Ge-like Re ions using the multiconfiguration Dirac–Hartree–Fock method. Energy levels, transition probabilities, weighted oscillator strengths, line strengths, and wavelengths are given for Zn-like, Ga-like, and Ge-like Re ions. Breit interactions and quantum electrodynamics corrections are taken into consider. Comparisons are performed between the calculated energy levels and wavelengths with other available values, which show that the calculated results are in good agreement with each other for Zn-like Re ions. And the spectral parameters of Ga-like Re and Ge-like Re are also calculated which are new and unpublished previously.
