Resonance strength for<i>KLL</i>dielectronic recombination of hydrogenlike krypton

Abstract

We report KLL dielectronic recombination (DR) resonance strength for hydrogenlike krypton ${\mathrm{Kr}}^{35+}$ measured with an electron-beam ion trap. X rays emitted from both DR and radiative recombination (RR) are observed as a function of electron-beam energy over the KLL resonances. The DR resonance strength is obtained by normalizing the DR x-ray counts to theoretical RR cross sections. The experimental strength is shown to agree with theoretical strength calculated using the flexible atomic code.
