Referring to the interview with Sveinn Ólaffson, I am wondering why he mentioned that when muon are stopped X-rays and/or gamma radiation should be detected (in the video at around 20:00 minutes).
Muons normally decay after approximately 2.2 us into electrons, muon-neutrinos and elektron-neutrino.
When I look at wiki there is no mentioning of X-rays or gamma radiation, so these effects should then occur when stopping muons before they decay. But what does stop mean in such case? I would expect they replace electrons of atoms that form the mass that stop muons, which in turn could create transmutations. Is it the transmutations that cause these X-rays and gamma radiations? This also the reason why I asked Holmlid whether he detected any transmutations in his setup.
If I understand correctly Holmlid applied a scintillator to stop muons. Why did he not detect and report X-rays and gamma radiation? Maybe I missed this.
Atomic muon capture knocks out electrons as the muon descends towards lower orbitals. This causes the emission of characteristic X-rays (up to several MeV) which depend on the element.

Initially Holmlid reported a beta-like signal which was thought to be due to nuclear capture reactions, but then he proposed a different mechanism here: https://www.researchgate.net/p…by_lepton_pair-production
I don't recall X-rays from atomic capture being mentioned in the process.
