tuumaühendusi
Tuumaühendusi, often translated as nuclear compounds or nuclear complexes, refers to arrangements of atomic nuclei that are bound together by nuclear forces. These are not stable, everyday molecules formed by electron interactions, but rather transient states that can arise in high-energy nuclear reactions or as intermediate steps in nuclear processes. The term is sometimes used in the context of nuclear astrophysics, where it can describe temporary groupings of nucleons (protons and neutrons) that play a role in stellar nucleosynthesis or the formation of heavier elements.
These configurations are distinct from stable atomic nuclei. Instead, they represent short-lived associations that exist for
