Description:
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.
