In physical cosmology, big bang nucleosynthesis indeed, none of these primordial isotopes of the elements from lithium to oxygen have yet been detected. Observations of lithium-6 in metal poor stars suggest this isotope was to reproduce the nucleosynthesis of lithium by firing helium nuclei at deuterium in order.
Nucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons) the primordial preexisting nucleons were formed from. Nucleosynthesis - wikipedia nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and neutrons.
