Artificial radioactivity in the nonequlibrium plasma of the glow discharge in Pd-D and Ni-H from the point of view of nuclear-chemical reactions

It is shown that artificial radioactivity can be initiated in conditions of nonequlibrium plasma glow discharge. The analysis of the isotope and elemental composition in the near-surface layers of Pd and Ni, the original and after 40-hour exposure in deuterium- or protium containing plasma by the IСP mass spectrometry (IСP-MS) has revealed significant changes in isotope composition of impurity elements.

Significant reduction in Pt and Pb impurities in Pd-D systems in times have been found. In addition, an increase in the content of W isotopes was found in the Pd-D system, which correlated with a decrease in the content of Pt isotopes.

In the Pd-D experiment the content of Pb isotopes (masses 206, 207, 208) decreased by ~ 200 times and Pt isotopes by ~ three times, and in the Ni-H experiment, Fe (by ~3-10 times) and Zn (from 20 to 1000 times).

Updated No Internal Trolling Rules for FR per Jim Robinson

If someone says stop, then stop. Do not enter onto a thread on a topic you don’t like just to disrupt, rattle cages, poke sticks, insult the regulars, or engage in trolling activities, etc. ~Jim Robinson

The issue isn’t whether we allow skepticism, it is whether we allow hyperskeptics and skeptopaths to ruin the scientific dialog. Such FReepers who persist in polluting these threads have been asked to leave, and we are asking that they open their own threads if they have comments.

This topic has a following, people who wish to learn and discuss the materials presented.

Please refrain from posting anything that doesn’t legitimately address the issue.

Something is going on in this segment of science. There are a considerable number of research groups studying the matter.
