Transition probabilities for [Ni I] and [Ni II] lines. J/A+AS/119/99 J/A+AS/119/99 [Ni I] & [Ni II] transition probabilities Transition probabilities for [Ni I] and [Ni II] lines. P Quinet M Le Dourneuf Astron. Astrophys. Suppl. Ser. 119 99 1996 1996A&AS..119...99Q Atomic physics atomic data Ni I Ni II transition probabilities New radiative transition probabilities have been calculated for forbidden lines of astrophysical interest in Ni I and Ni II. The accuracy of the transition probability scales is established on the basis of two independent calculations performed with the approximately relativistic Hartree-Fock (HFR) and SUPERSTRUCTURE (SST) codes. Both physical models take into account the most important configuration interaction (CI) and relativistic effects.
