"High-precision wavelength measurements on the $1s2s\\ ^3S_1 \\rightarrow 1s^2\\ ^1S_0$ ($z$'') and $1s2p\\ ^1P_1 \\rightarrow 1s^2\\ ^1S_0$ ($w$'') transitions in Ar$^{16+}$ as well as of the Lyman-$\\alpha_1$ transition in Cl$^{16+}$ with respect to the Lyman-$\\alpha_1$ transition in Ar$^{17+}$ were carried out, using a new flat crystal spectrometer installed at the Heidelberg electron beam ion trap (HD-EBIT). A novel, highly accurate technique of Bragg-angle determination was developed, employing two beams of visible light reflected on the x-ray crystal to mark the x-ray reflection position. The need for collimating entrance slits causing unacceptable x-ray flux losses is thereby avoided. Relative uncertainties of better than $\\Delta \\lambda / \\lambda < 10^{-5}$ were achieved in the measurement of all three lines. The measured Cl$^{16+}$ Lyman-$\\alpha_1$ transition energy is in perfect agreement with the theoretical prediction and previous experimental work, however $4$ times more accurate. The $z$ transition energy, never measured before in argon, agrees with predictions within its error bar. The $w$ transition energy, while in perfect agreement with but two times more accurate than earlier experimental results, disagrees with by $2\\sigma$ with predictions, pointing at their possible incompleteness."^^ .
