Material as a Co-Author of the Nuclear Event: SCCM Predictions for Material-Controlled Low-Energy D–D Fusion

This preprint develops a falsifiable SCCM-based interpretation of material-controlled low-energy deuterium–deuterium fusion in palladium and titanium matrices. The work is motivated by experiments in which the fusion yield ceases to decrease exponentially below approximately 2.5 keV and forms a low-energy plateau that cannot be fully reproduced by a constant electron-screening potential alone. Within the Semon–Causon Causality Model (SCCM), the observed reaction rate is represented as the sum of a standard screened-fusion channel and an additional material-dependent channel governed by the effective structural projection (\sigma_{\mathrm{eff}}), local coherence (\alpha_s), effective dimensionality (D_{\mathrm{eff}}), defect correlation scale, and beam activation conditions. The paper presents ten experimentally distinguishable predictions, including a second low-energy turnover, an optimum rather than maximum defect density, dependence on beam pulse structure, coherent-excitation resonances, non-Poissonian event statistics, and universal scaling through the ratio of penetration depth to defect-correlation length. The manuscript also provides a numerical illustrative model, normalized prediction curves, comparison with competing explanations, a step-by-step experimental protocol, and explicit falsification criteria. The proposed SCCM contribution is not treated as evidence for self-sustaining “cold fusion” and does not replace established nuclear physics. It is formulated as an additional, testable statistical mechanism describing how the local material structure may participate in determining the probability of a nuclear event. The deposited record contains two equivalent versions of the preprint: Russian and English. All numerical curves are illustrative and are not claimed to be a fit to the original experimental data.
