Two light nuclei combine into a heavier nuclear product, with energy released for exothermic channels when the final products have greater total binding energy.
Fusion requires overcoming or tunneling through the Coulomb barrier and is not exothermic for every choice of reactants and products.

This is an authored directed relation from the source endpoint to the target endpoint.
Require a quantum-mechanically allowed product channel; Coulomb-barrier penetration controls the reaction rate, and energy is released only for exothermic channels.
Feed several structures into a construction junction and impose compatibility between them.

This is an authored directed relation from the source endpoint to the target endpoint.
Big Bang nucleosynthesis includes fusion and capture reactions among light nuclei, coupled to weak processes and cosmic expansion rather than occurring as an isolated laboratory fusion reaction.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
