Collision strengths for transitions in Ni XIX

In this paper we present calculations of electron impact excitation collision strengths for transitions among the 89 fine-structure levels of the 2S(2) 2p(,)(6) 2S(2) 2P(5) 3l, 2s(2)p(6) 3l, 2s(2) 2p(5) 4l, and 2s(2)p(6) 2l configurations of Ni XIX, for which flexible atomic code (FAC) has been adopted. Comparisons are made with the earlier available results in the literature, and the anomalies observed have been discussed.
