Accurate Wavelength Measurements of He-Like Resonance Lines of Titanium through Zinc from a High-Temperature Plasma

抄録

Kα lines of titanium through zinc have been observed from a high-temperature plasma in a vacuum spark. The transition wavelengths of the He-like resonance lines are first determined under careful experimental procedures. The result is compared with theoretical predictions and is in good agreement with that given by Safronova. The theoretical values, however, include uncertainties in relativistic and QED corrections of the He-like resonance line. More accurate theoretical values are required for comparison with these experimental data.
