Elementa Mirabilia

This catalogue documents atomic nuclei that exhibit anomalous nucleosynthetic, structural, or isotopic behaviors within the Universal Nucleosynthesis (UNS) framework. Grounded in a Boerdijk–Coxeter (BC) helical assembly model and 21 diagonal Nuclear Synthesis Expressways, Elementa Mirabilia systematically cross-checks elements across structural parameters: geometric closure states, nucleon-pair (A-2) rules, isotopic abundance anomalies, radioactive bridge relays, dynamic Centre of Mass mechanics, and supernova fusion channels. From the odd-A abundance dominance of Platinum (Z=78) and the ten-isotope crankshaft haven at Tin (Z=50), to the geometric stability gaps of Technetium (Z=43) and Promethium (Z=61), this document establishes the deterministic geometric logic governing nuclear anomalies across the periodic table.
