Let's see. Fifty years....that would mean that the scientific basis to make such calculations originated around 1960. The muon was discovered in 1936. So to develop the capacity took about forty years. And research into the properties of the muon wasn't artificially impeded by an active campaign to deny funding or academic positions to any who dared to do such research.
The Pons/Fleischmann experiment was in 1988. So CF should be due to reach that level of theoretical prediction capability around 2025. Given the current rapid strides being made in understanding the mechanisms of LANR in spite of the artificial barriers currently in place on such research, I think LANR will beat out "muon catalyzed CF" by quite a few years in reaching that capability.
Oh, and here's a trivia tidbit for you......what was the ONLY proven case of fraud in cold fusion research??? (Hint...it's NOT Rossi).
Andrei Sakharov and F.C. Frank [3] predicted the phenomenon of muon-catalyzed fusion on theoretical grounds before 1950. Yakov Borisovich Zel'dovich[4] also wrote about the phenomenon of muon-catalyzed fusion in 1954. Luis W. Alvarez et al.,[5] when analyzing the outcome of some experiments with muons incident on a hydrogen bubble chamber at Berkeley in 1956, observed muon-catalysis of exothermic p-d, proton and deuteron, nuclear fusion, which results in a helion, a gamma ray, and a release of about 5.5 MeV of energy. The Alvarez experimental results, in particular, spurred John David Jackson to publish one of the first comprehensive theoretical studies of muon-catalyzed fusion in his ground-breaking 1957 paper.[6] This paper contained the first serious speculations on useful energy release from muon-catalyzed fusion. Jackson concluded that it would be impractical as an energy source, unless the "alpha-sticking problem" (see below) could be solved, leading potentially to an energetically cheaper and more efficient way of utilizing the catalyzing muons.[6] This assessment has, so far, stood the test of time.So it only took a year from the first observation of muon catalyzed cold fusion in 1956 to accurately explaining it theoretically. The quackery you promote is way behind that timetable.
