Measurement of 1s2s[sup 3]S[sub 1]-1s2p[sup 3]P[sub 2,0] intervals in helium-like neon

We have measured the vacuum ultra-violet 1s2s[sup 3]S[sub 1]-1s2p[sup 3]P[sub 2,0] transition wavelengths in helium-like neon by photographic spectroscopy of a recoil ion source. The results are 1248.01 [plus minus] 0.01[Angstrom] and 1277.74 [plus minus] 0. 04[Angstrom] respectively and are a sensitive test of present relativistic and quantum electrodynamic calculations.
