Mark, Fran This kind of basic hydrogen transition testing has been going on for three or four decades as kind of a “competition” between various labs for one-upmanship; and as your surmise it is important because the Rydberg constant can be deduced from this value. But the practical value is almost past-tense - kind of like determining Pi to greater and greater precision.
How the Rydberg constant relates to the 15 Terahertz figure - which has turned up in recent analysis as being relevant to LENR isn't clear. I've convinced myself that it is connected, but the details beyond Plasmonics/Polaritons are murky. However, I should add that the explanation probably goes deeper than an effort to apply it to 24 MeV and helium (I’m not saying it's curve-fitting – only that the frequency applies to Ni-H via Plasmonic and IRH). The Rydberg is one of the most important constants in all of physics and probably the most important of all for understanding Ni-H LENR – to the degree that one subscribes to any variation of the f/H theory (ostensibly a non-nuclear version with fractional hydrogen based to some degree on the hydrogen ground state redundancy of Mills). Twenty years ago, we had essentially the same numerical value, and it hasn’t changed by much over the original: http://www.maik.ru/full/lasphys/94/2/lasphys2_94p302full.pdf A value of the Rydberg constant = 109737.3156846 cm−1 is still good enough for government work. From: Roarty, Francis X Mark, Nice find! It should reveal sub harmonics for manipulating h but regarding f/h it brings up an interesting question, does the spectrum broadening mean the fractional orbits are at different frequencies, and if so are they nice orbital steps ½ to 137? Or is the shift linear? Fran From: MarkI-ZeroPoint http://physics.aps.org/synopsis-for/10.1103/PhysRevLett.110.230801 ----------------------------------------- Light emission from hydrogen atoms allows spectacularly precise confirmation of quantum-mechanical laws. But theorists have yet to fully reconcile those laws with relativity, the other major foundation of modern physics. In Physical Review Letters, a multilaboratory collaboration reports improved hydrogen measurements that place limits on how big one possible correction to relativity could be. Researchers at the Max Planck Institute for Quantum Optics in Garching, Germany, have pioneered methods that connect optical emission frequencies to the much lower radio frequencies of atomic clocks. But the best atomic clocks, based on a fountain of cesium atoms, are in distant labs such as the Federal Physical-Technical Institute (PTB) in Braunschweig, and can’t be easily moved. So the two labs synchronized their setups by sending light signals back and forth over a 920-km-long optical fiber. The connection allowed them to express the 1S-2S transition frequency in terms of the international standard definition of the second as 2,466,061,413,187,018 hertz, with an uncertainty of just 11 hertz. The researchers exploited the unprecedented precision to look for variations of the frequency over a year. Such variations would show that the frequency depends on the motion of the Earth around the Sun, which is forbidden by relativity. But the team estimates that parameters that quantify that dependence can be no larger than a few parts in 10^11. One of the parameters is slightly different from zero, but even more precise measurements will be needed to determine if this difference is truly significant. – Don Monroe --------------------------------------------- Will a photon of that same frequency cause a 1S-2S transition??? Now you have an exact frequency with which to manipulate the H atom… -Mark Iverson
