Title: Measurement of the Lamb shift in heliumlike uranium (U/sup 90 +/)

Abstract

The production in 1983 of a beam of bare U/sup 92 +/ at the Lawrence Berkeley Laboratory's Bevalac, the Bevatron and Super-HILAC operating in tandem, demonstrated the feasibility of experiments using few-electron uranium. In 1984 x rays from radiative electron capture into the K shell of uranium was observed by Anholt et al., and in the same year x rays from n = 2 ..-->.. n = 1 transitions in hydrogenlike uranium (U/sup 91 +/) and heliumlike uranium (U/sup 90 +/) were observed by Munger and Gould. This article discusses our recent measurement of the Lamb shift in heliumlike uranium. Our value of 70.4 (8.1) eV for the one-electron Lamb shift in uranium is in agreement with the theoretical value of 75.3 (0.4) eV. 20 refs., 5 figs.
