摘要
We conducted high-precision measurements of the wavelength of a 4d(1)S(0) --> 4p(1)P(1) line of a nickel-like silver X-ray laser. The Lyman series lines of hydrogen-like helium ions emitted from low-density plasmas were used as wavelength references, and the wavelength of the X-ray laser line was determined to be 13.887 nm (+/-0.002 nm). The experimental results were compared with Multiconfiguration Dirac-Fock calculations and were found to agree with theoretical wavelengths.
