Paraphrased abstract of new Holmlid paper - Published 18 October 2016. It is paraphrased since the original wording assumes familiarity with a long string of earlier work.
This would be the most important experimental work in all of physics (including the over-hyped LHC experiments, etc.) IF IT WERE TO BE FULLY REPLICATED by an independent, respected Lab. There is no high quality replication to date. In fact, it is generally ignored. This work is a continuation of the line of research using a low powered laser (yellow-green spectrum) to irradiate "ultra-dense hydrogen" or UDH which has been formed and deposited in situ in a catalyst. Prior work focused on dense deuterium; this is protium. Despite similarities this active target is not the Mills hydrino, although there are similarities. The catalyst is iron-oxide based. Kaons and pions are observed by their characteristic decay times of 12, 52 and 26 ns after impact of relatively weak ns-long laser pulses, as reported previously. Deflection of emitted particles in a weak magnetic field or penetration through metal foils cannot distinguish between the (supposed) decaying mesons. The signals observed are primarily not caused by decay but by fast particles, often at >50MeV, formed in pion decay. The fast particles are concluded to be muons from their relatively small magnetic deflection and strong penetration. This is further supported by published studies on the direct observation of the beta decay of muons in scintillators and solid converters.
