Problem 6.139

What metal has in its absorption spectrum the difference between the frequencies of X-ray \(K\) and \(L\) absorption edges equal to \(\Delta \omega=6.85 \cdot 10^{18} \mathrm{~s}^{-1} ?\)

Reveal Answer
Z=1+4Δω/3R=22, titanium. Z=1+\sqrt{4 \Delta \omega / 3 R}=22, \text { titanium. }
