英文摘要	The fine structure and ionization energy of the 1s2s2p P-4 state of the helium negative ion He- are calculated in Hylleraas coordinates, including relativistic and QED corrections up to O(alpha(4)mc(2)) , O(mu/M)alpha(4)mc(2)), O(alpha(5)mc(2)), and O(mu/M)alpha(5)mc(2)). Higher order corrections are estimated for the ionization energy. A comparison is made with other calculations and experiments. We find that the present results for the fine structure splittings agree with experiment very well. However, the calculated ionization energy deviates from the experimental result by about 1 standard deviation. The estimated theoretical uncertainty in the ionization energy is much less than the experimental accuracy.
