There are nuclear decays and there are decays of excited atomic orbitals and there are decays of excited molecular orbitals. Here is the title of a paper: "Decay of spin-polarized atomic hydrogen in the presence of a Bose condensate" > Decay normally unvolves a nuclear transition.

Here is a quote from a different paper: "Laser excitation to near-threshold continuum states is found to result in non-exponential decay of the ground state population." http://www.optics.rochester.edu/users/stroud/thesis/cardimona.html -- bz please pardon my infinite ignorance, the set-of-things-I-do-not-know is an infinite set. bz+sp(a)ch100-5.chem.lsu.edu remove ch100-5 to avoid spam trap

Two reasons. 1) the aparatus constitutes an EM FoR and 2) the methods used to measure the OW speeds of Xray and gamma particles is suspect.

Just enough to show > that no photons faster than c. It doesn't take much >accuracy to show that photons are not traveling at 1.9 c. Correction: 1.2 c, as I understand the pi meson experiment. However, I'm now having trouble finding a web page describing that particular experiment. (Feh!!) One webpage that mentions mesons in a different context (as it's explaining the time dialation issue) is http://www.upscale.utoronto.ca/GeneralInterest/Logan/Poetry/CHAPTER11-12.html which can also be taken as good evidence for SR. -- #191, ewill3(a)earthlink.net It's still legal to go .sigless.
