摘要
We report the experimentally determined KLL dielectronic-recombination (DR) resonance strengths of Li-to O-like gold. The measurement was performed with an electron beam ion trap, and the x rays emitted from DR and radiative recombination (RR) were both observed. The DR resonance strengths were determined by normalizing DR x-ray intensities to the theoretical RR cross sections. The experimental DR resonance strengths are compared with the theoretical ones, and the comparison shows a good agreement. The scaling laws of the KLL DR resonance strengths were obtained as a function of atomic number for B-like and C-like ions by fitting the present and existing experimental results.
