Measurement of 
wavelengths in helium-like sulphur
D J H Howie
, J D Silver and E G Myers
We have used photographic spectroscopy of a beam - foil source to measure the vacuum ultraviolet 1s2s 
- 1s2p 
transition wavelengths in helium-like sulphur. The results are 
Å and 
Å, respectively. These measurements, together with our earlier measurements in helium-like silicon and phosphorus, are compared with other precision measurements for Z = 14 to 18, and with recent relativistic and quantum electrodynamic calculations.
