Calculated transition probabilities (A-values) and log(gf)s for electric dipole transitions of Ni II.

This dataset corresponds to Table A2 in the paper “Calculated oscillator strengths and transition probabilities of singly ionised nickel (Ni II)” by C. P. Clear et al., published in Astronomy & Astrophysics (2026). It contains the calculated transition probabilities (A-values) and oscillator strengths (log(gf)) for electric dipole (E1) transitions of singly ionised nickel (Ni II). These values were obtained using the orthogonal operator method, as detailed in the publication. The table includes transitions between observed and predicted energy levels, providing essential atomic data for astrophysical and laboratory plasma modelling.
