In series of different experiments with laser irradiation (sometimes combined with electrolysis) of hydride-forming metallic targets immersed in D2O, Barmina et al. claim to have observed both production and so-called “accelerated decay” of Tritium. If correct, their claimed detection of significant amounts of radioactive Tritium production is an extremely interesting experimental result because over the past 24 years, out of the hundreds of thousands of LENR experiments conducted, literally only a handful have ever claimed to observe Tritium as a measurable nuclear product. In separate very recent publications (2012, 2013), Barmina et al. claim to have developed a theory which can explain all their experimental data; their theoretical approach includes ‘new nuclear physics’ and exotic concepts such as a so-called “in-shake-up” nuclear state that enables production of new bound di-/tri-neutron particles.
Presuming that their experimental data are shown to have been correctly measured and results are successfully repeated by other independent researchers, their reported data provides further confirmation of Widom-Larsen theory of LENRs in a type of laser-based LENR experimental system pioneered by Letts & Cravens (USA) ca. 2002 – 2003.
During the past decade or so, there have also been increasing numbers of experimental reports published in various peer-reviewed journals in which authors claimed to have observed changes in intrinsic nuclear decay rate constants of certain isotopes/elements.
Importantly, there is probably a subset of such anomalous reported data in which experimentalists were blithely unaware of any possibility that LENR transmutations could be occurring inside their experimental systems. In such cases, the measured parameter(s) indicating a given nuclear decay rate, say intensities of a series of gamma emission lines, changes because the isotope(s) producing the gammas being measured has/have simply captured W-L ULM neutrons and been transmuted to other different --- perhaps even stable --- isotope(s); ergo, measured isotopes’ intrinsic nuclear decay rate constants did not really change during such types of experiments. Thus, the long-mysterious “Reifenschweiler effect” could in reality be just conversion of Tritium into neutrons that are captured by, among other things, substrate atoms..
