Abstract:
In this paper we report calculations for energy levels, radiative
rates and excitation rates for transitions in NiXI. The GRASP
(General-purpose Relativistic Atomic Structure Package) and FAC
(Flexible Atomic Code) have been adopted for calculating energy levels
and radiative rates, and the Dirac Atomic R-matrix Code (DARC) has
been used to determine the excitation rates. Oscillator strengths,
radiative rates and line strengths are reported for all E1, E2, M1
and M2 transitions among the lowest 250 levels of NiXI. Additionally,
lifetimes are also reported for all levels. However, results for
excitation rates are presented only for transitions among the lowest
17 levels.
