From: Stephen Cooke * Could there be characteristic photon emission from transitions in muon shell levels similar to those from electrons and at what frequencies these occur. Could these be observed experimentally? If characteristic radiation can be seen from muon energy level transitions then it could be interesting to see if radiation of these frequencies occur astronomically.
A fraction of typical Cherenkov radiation in fission reactor spent fuel pools comes from muons. Someone out there probably knows the exact signature frequency of light originating from muons in that situation, both the initiating frequency and the downshifted, but I do not. This signal is detected astronomically as well. There are Cherenkov detectors made specifically for atmospheric detection. And yes - this signature could probably be used as further evidence of muons - by replicators of Holmlid - most of whom do not have access to muon detectors. Although observed to be blue, most Cherenkov radiation is actually in the ultraviolet spectrum, downshifted to visible blue by the water interaction. It would be interesting to position a "glow tube" experiment in a water bath and try to isolate the characteristic signal of muons using filters and spectrometers, but the signal could be overwhelmed by the intensity of IR.
