[time-nuts] Re: Creating a D.I.Y Rubidium Atomic Clock

[Richard Karlquist]

My understanding is that the Rb85 and Rb87 isotopes happen to
accidentally be correct to make the optical filter cell work correctly. 
I don't believe you can do this with any other atom.  It's different
from primary atomic standards that just excite the hyperfine quantum
transition.  In that case, you can debate about which atom or ion to
use.
