TY - JOUR ID - citeulike:5921584 L3 - citeulike-article-id:5921584 N2 - The 2 3P1–2 3P2 interval in helium is measured using microwave separated oscillatory fields. Our measured result is 2 291 177.53±0.35  kHz . A disagreement with theory of over 15 kHz indicates a major problem with two-electron QED calculations. If this disagreement is resolved, measurements of both 2 3P fine-structure intervals at this accuracy would lead to a six-parts-per-billion determination of the fine-structure constant.
