Abstract
A measurement of the 1s2p →1 resonance transition in heliumlike germanium () has been made on the Lawrence Livermore National Laboratory electron-beam ion trap to a precision of 21 ppm. The result is compared with theoretical values and confirms a trend previously seen in the differences between experiment and theory for this transition as a function of Z. Results for the 1s2p →1 and 1s2p →1 intercombination lines and for the 1s2s →1 forbidden line are also presented and show similar differences with theoretical predictions.
