Measurement of the 3 s 1 / 2 - 3 p 3 / 2 resonance line of sodiumlike Eu 52 +
We have measured the 3s 1/2 -3p 3/2 transition in sodiumlike Eu 52+ situated at 41.232 Å with an uncertainty of 73 ppm. Our measurement extends previous high-precision measurements into the 56< Z< 78 range of atomic numbers. We also present measurements of 3s 1/2 -3p 3/2 and 3p 1/2 -3d 3/2 transitions in the neighboring magnesiumlike, aluminumlike, and siliconlike europium ions.
