摘要：

High-resolution measurements of dielectronic recombination cross sections for neonlike xenon (Xe44+) are presented. The experimental method consists of the formation and interaction of ions with electrons in an ion trap followed by an analysis of the extracted ions to determine relative yields. Low beam currents are used to obtain an energy resolution of 16 eV FWHM. Reductions in the number of initial ions of more than 3 orders of magnitude are observed as the strongest resonances are scanned. The relative contributions of the LMM, LMN, LMO, LMP, and LMQ groups of resonances are compared to theoretical calculations. The agreement with theory is excellent.
