摘要The KLL dielectronic recombination processes of highly charged He-like to C-like Kr ions have been studied experimentally. The measurement was performed on the newly developed Shanghai electron beam ion trap (Shanghai-EBIT) facility. Characteristic x-rays from both dielectronic recombination and radiative recombination are detected as the electron beam energy is scanned through the resonances. The KLL resonant strengths obtained are 5.41×10-19, 4.33×10-19,3.59×10-19,2.05×10-19 and 0.98×10-19cm2eV for He-like to C-like Kr ions, respectively.
