المستخلص: Recently, gold highly charged ions are of great interest in low and high density plasma experiments. In order to better understand the experimental features of the Au spectra and to identify the transition lines, This research focused on producing atomic data and spectra with identification of the spectral features of some selected Au ions: Ne- like Au (Au69+ ), F- like Au (Au70+ ), O- like Au (Au71+ ) and N- like Au (Au72+ ) ions. The fully relativistic multi-configuration interaction method used to produce atomic structure and spectra database for the selected Au ions. The used codes are HTAC program which is based on FAC atomic code The analysis of four Au ions synthetic spectra for electric dipole transitions showed the presence of a wide variety of ionization stages from N-like to Ne-like Au in the spectral range 0.5Å - 1.4 Å. The majority of the lines in the N like Au spectra was identified and assigned to the 2s→np and 2p→ns transitions. The line of O-like Au includes different and overlapped groups of transitions which are 2p-nd, 2p-ns transitions. While the spectral lines for F-like Au identified as 2p-nd and 2s-np and 2p-ns transitions and for N –like Au the transitions are 2p-nd. Oscillator strengths, and transition rates and wavelengths were calculated for electric-dipole (E1) and electric-quadruple (E2) and electric octuepole (E3) transitions and magnetic-dipole (M1) and magnetic-quadruple (M2) and magnetic octuepole (M3) transitions in Au ions from Au+72 to Au+69 ions by using the fully relativistic multi configuration interaction method. The produced atomic data were tabulated and discussed to be ready to use as a database for the selected Au ions.The resulting transition energies of Ne-like Au were compared with other recent published data and showed a good agreement.
