In this paper we report calculations for energy levels, radiative rates, and excitation rates for transitions in O IV.
The GRASP (general-purpose relativistic atomic structure package) and FAC (flexible atomic code) we adopted for calculating energy levels and radiative rates, and the Dirac atomic R-matrix code (DARC) used to determine the excitation rates.
Oscillator strengths and radiative rates are reported for all E1, E2, M1, and M2 transitions among the lowest 75 levels of O IV. Additionally, lifetimes are reported for all levels and comparisons made with those available in the literature. Finally, effective collision strengths are reported for all transitions over a wide temperature range below 106K. Comparisons are made with earlier results and the accuracy of the data is assessed.
