Abstract

The spectra from Fe-peak elements may be used to determine the temperature and density of various 
astrophysical objects. Determination of these quantities is underpinned by the accuracy and the 
comprehensiveness of the underlying atomic structure and collisional calculations. In the following paper, 
we shall focus specifically on Ni IV lines associated with transitions amongst several low-lying levels. We 
shall employ modified versions of the parallel Dirac R-matrix codes, considering both electron-impact 
excitation of Ni3+ and the photoionization of both the ground and excited states of Ni2+. We produce 
high-quality data sets for both processes, and using these data, we calculate line ratios relevant for 
plasma diagnostics of temperature and density.
