Abstract

This research note evaluates the validity and temporal dynamics of the transition from chemical exothermic reaction paths to nuclear fusion in condensed matter systems. Evidence suggests that intense mechanical compression of fuel mixtures can trigger internal shear friction, creating localized "hot-spots" that ignite exothermic chemical reactions. These precursors, such as the formation of MnP (104 kJ/mol) and Ca₃P₂ (543 kJ/mol), provide the localized thermal energy and fuel dissociation required to bridge the energy gap to the nuclear regime through enhanced Coulombic screening. The temporal sequence of the process is characterized by three diagnostic phases: leading indicators (chemical heat and soft X-rays), real-time signatures (prompt MeV neutrons and hardX-rays), and lagging indicators (total fusion yield and calorimetry). Although physically generated MeV neutrons are the definitive proof of a nuclear transition, their detection involves inherent latencies due to Time-of-Flight (T-o-F)
effects and moderation requirements, frequently categorizing the observed signal as a post-event indicator. This analysis clarifies the leading and lagging roles of nuclear signatures in validating solid-state fusion events. The proposition that nuclear fusion energy processes can originate from chemical exothermic reaction paths represents a significant departure from conventional high-energy plasma physics, yet it finds substantial grounding in the emerging field of condensed matter nuclear science. This report examines the validity of the statement that chemical triggers can bridge the gap to nuclear transitions, specifically when such processes result in the physical generation of mega-electron-volt (MeV) neutrons. By analyzing the thermodynamic, mechanical, and quantum mechanical requirements for such a transition, and by deepdiving into the temporal chronology of fusion signatures, this analysis provides a definitive framework for understanding whether MeV neutron detection serves as a
leading, real-time, or lagging indicator of nuclear events.
