I'm reading some papers on recent measurements of the hydrogen 1S-2S transition frequency, and they report 2466.061 THz (with about nine additional digits of precision ). However, when I calculate this frequency from the "exact fine-structure formula for hydrogen" (using 1S(n=1,j=0) and 2S(n=2,j=0) I get 2467.554 THz. Has anyone here computed a theoretical value for this transition frequency, and if so what number did you get?(adsbygoogle = window.adsbygoogle || []).push({});
