采用最近发展的组态相互作用与微扰理论相结合的方法（CIPT方法，Dzuba et al，Phys. Rev. A，{\bf 95}，012503（2017））计算了超重元素dubbion（Db，Z=105）的原子光谱和其他性质。这些包括低位态的Db和Db~II的能级，从基态的Db的电偶极跃迁振幅，这些跃迁的同位素位移和电离电位的Db。对Ta进行类似的计算，Ta是Db的较轻类似物，以控制计算的准确性。
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 lighter analog of Db, are performed to control the accuracy of the calculations.
