Fine Structure of Helium
Under the expectation that experiments will soon give values for the 6ne structure intervals of the 2'I" state of helium to an accuracy of 1/10', we have undertaken a program of calculations which, it is hoped, will lead to a new determination of the 6ne-structure constant n. This paper gives a brief survey of the over-all program, and a detailed report of the successful completion of the', 6rs...
متن کاملThe helium fine-structure controversy
There is presently disagreement between theory and experiment as well as between different theoretical calculations concerning the fine-structure splitting of the lowest P state of the neutral helium atom. We believe that we have found a minor error in the formulas used by Drake et al. (Can. J. Phys. 80, 1195 (2002)) in their calculations, and we may have an explanation how the error has occurr...

متن کاملFine structure of helium and light helium-like ions
Calculational results are presented for the fine-structure splitting of the 2P state of helium and helium-like ions with the nuclear charge Z up to 10. Theoretical predictions are in agreement with the latest experimental results for the helium fine-structure intervals as well as with the most of the experimental data available for light helium-like ions. Comparing the theoretical value of the ...
متن کاملImproved theory of helium fine structure.
Improved theoretical predictions for the fine-structure splitting of 2(3)PJ levels in helium are obtained by the calculation of contributions of order alpha5 Ry. New results for transition frequencies nu(01) = 29616943.01(17) kHz and nu(12) = 2291161.13(30) kHz disagree significantly with the experimental values, indicating an outstanding problem in bound state QED.
