Observation of KLM dielectronic recombination resonances in highly charged uranium ions

摘要

We have observed the KLM and higher (Delta)n (ge) 1 dielectronic recombination resonances in highly charged (near-heliumlike) uranium ions. The resonances were observed via photon emission from ions trapped in an electron beam ion trap (EBIT). As the energy of the electron beam was swept over the resonances, characteristic radiation from dielectronic recombination was recorded in photon detectors.
