Abstract
Relativistic configuration interaction calculations with the inclusion of Breit interaction, quantum electrodynamics and finite nuclear mass corrections have been carried out in the extended optimal level scheme using multi-configuration Dirac-Fock wavefunctions on the wavelengths, electric dipole transition rates, line strengths and oscillator strengths of nickel. Through the use of the active space method, the calculated values are compared with the other available data on He-like and Be-like nickel and are found to be in very good agreement with them. In this paper we give accurate transition properties from NiXIX through NiXXVII. These data provide reference value for level lifetime, charge state distribution and average charge of nickel plasma.
