Hi Antonio, Perhaps I shouldn't have used the word "strongly". Here are real numbers instead -- a typical Cs beam tube has a 53 kHz splitting (compare with the 9 192 631 kHz center peak) when the C-field is 76 milligauss. Here's an old time nuts thread about Zeeman frequencies: http://www.mail-archive.com/[email protected]/msg00233.html If you want to see the peaks for yourself, see this experiment: http://www.leapsecond.com/pages/cspeak/ And my favorite, a large color plot of peak splitting vs. C-field: http://www.leapsecond.com/images/cfield.gif /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
