Precision measurement of relativistic and QED effects in heliumlike beryllium

Abstract

We have used fast-ion-beam laser spectroscopy to measure the 1s2s 3 S-1s2p 3 P o intervals in Be III to an absolute accuracy of 1 part in 10 8 . Our results are (in cm -1 ): σ(1s2s 3 S 1 -1s2p 3 P 0 o )= 26 864.6120(4), σ(1s2s 3 S 1 -1s2p 3 P 1 o )=26 853.0534(3), σ(1s2s 3 S 1 -1s2p 3 P 2 o ) =26 867.9484(3). These results are an improvement over previous measurements by nearly 3 orders of magnitude and show evidence of uncalculated O(α 4 Z 4 ) relativistic corrections
