Analysis of E3 Transitions in Ag-like High-Z Ions Observed with the NIST EBIT.

We report measurements and identification of the E3 4f 7 / 2 , 5 / 2 -5s 1 / 2 transitions and E1 allowed transitions in Ag-like W (Z = 74), Re (Z = 75), and Ir (Z = 77). The spectra were recorded at the NIST EBIT using a grazing-incidence EUV spectrometer. The present measured wavelengths and theoretical predictions using GRASP2K calculations confirm previous observations of the same E3 transitions in Ag-like W. Our collisional–radiative model using the NOMAD code offers an insight into the population kinematics for Ag-like ions of heavy elements. We discuss the observed spectra and comparisons of the measured and simulated spectral lines. [ABSTRACT FROM AUTHOR]
