E-Cat SK and long-range particle interactions
Abstract: Some theoretical frameworks that explore the possible formation of dense exotic electron clusters in E-Cat SK are presented. Some considerations on the probable role of Casimir, Aharonov-Bohm and vacuum polarization effects in the formation of such structures are proposed. Dense electron clusters are introduced as a probable precursor for the formation of proton-electron aggregates at pico-metric scale, stressing the importance of evaluating the plausibility of special electron-nucleon interactions, as already suggested in . An observed isotopic dependence of a particular spectral line in the visible range of E-Cat plasma spectrum seems to conrm the presence of a specic proton-electron interaction at electron Compton wavelength scale.
