I can't give you an authoritative answer but google for the three words maser wall shift and you will see a large set of professional papers over the decades that explain the issue. I believe it is one of the main reasons that Cs thermal beams won out over H-masers in the 1960's decision over which method to redefine the SI second. H-masers could be made more stable but Cs beams could be proved more accurate. /tvb _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
