Exactly, and a BEC would probably have the sharpest line... but you would need some way to measure frequency with 1 in 10^15 accuracy. Not possible... yet. -Mark Iverson -----Original Message----- From: mix...@bigpond.com [mailto:mix...@bigpond.com] Sent: Saturday, June 22, 2013 6:31 PM To: vortex-l@eskimo.com Subject: Re: [Vo]:Mark has blazed the path In reply to MarkI-ZeroPoint's message of Sat, 22 Jun 2013 01:01:18 -0700: Hi, [snip] >Robin wrote: >" I would expect there to be a direct correlation between the Q and the >line width of spectral lines." > >That's one possibility... > >Another is that the actual line is much narrower than what you see, but >the frequency is varying about a mean so fast that it APPEARS to our >measuring instruments as a wider, single line. Then the spectral lines of substances close to absolute zero should be much sharper. Papers on low temperature spectrometry? Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
