摘要：

We revisit the discrepancy between experiments and theory for the x-ray transitions of heliumlike ions and report on a measurement of the n = 2 -> n = 1 x-ray transitions of heliumlike Cu27+. These measurements were carried at the Livermore electron beam ion trap facility and achieved an accuracy of 18 ppm. The measured values show reasonable agreement with theory, but they do not follow the trend established by other measurements with similar uncertainties.
