摘要
We have measured the channel-specific cross sections for dielectronic recombination (DR) via the KLn (n =2,...,5) resonance series of He-, Li-, and Be-like krypton ions. The measurements were made with an electron beam ion trap, and the DR Cross sections were determined relative to the cross section for nonresonant radiative recombination. In the present electron-beam ion-trap experiment, up to five charge states (He- to C-Like krypton) were detected in the trap. A fit procedure was used to compare the experimental data with theoretical calculations. The results agree well with the predictions. Additionally, the radiative relaxation mechanism following the stabilization transition in the dielectronic-recombination process was analyzed. The experimental approach used for measuring the DR excitation function opens up a spectroscopic method for the determination of the relative abundance of the highly charged ions.
