@article{Lackenby2018CalculationOA, title={Calculation of atomic spectra and transition amplitudes for the superheavy element Db ( Z =105)}, author={Bryce G. C. Lackenby and V. A. Dzuba and Victor V. Flambaum}, journal={Physical Review A}, year={2018} }

Atomic spectra and other properties of superheavy element dubnium (Db, Z=105) are calculated using recently developed method combining configuration interaction with perturbation theory (the CIPT method, Dzuba et al, Phys. Rev. A, {\bf 95}, 012503 (2017)). These include energy levels for low-lying states of Db and Db~II, electric dipole transition amplitudes from the ground state of Db, isotope shift for these transitions and ionisation potential of Db. Similar calculations for Ta, which is…
