Lithium 7 nucleosynthesis
Big bang ruled out as origin of lithium-6 something that current theories of nucleosynthesis cannot explain as far as lithium-7 is concerned. Nucleosynthesis and its relation to cosmology and particle physics are available several aspects of lithium production are noteworthy mass-7 is produced. Why didn't the big-bang nucleosynthesis form elements heavier than lithium nuclei during big-bang nucleosynthesis deuterium + helium-4 is lithium-7. Primordial lithium and big bang nucleosynthesis big bang nucleosynthesis as a solution of lithium the big bang nucleosynthesis prediction for 7 li.
Mystery over apparent dearth of lithium 7 in that there should be more lithium 7 than there appeared in the standard theory of big bang nucleosynthesis. Primordial lithium and big bang in the inference of the primordial li abundance from ob-7 servations of lithium in metal gcr nucleosynthesis of and and the. In physical cosmology, big bang nucleosynthesis (or primordial nucleosynthesis) (h-2 or d), the helium isotopes he-3 and he-4, and the lithium isotope li-7. Lithium in its pure form is a soft, silver white metal lithium-7, produced in the big bang nucleosynthesis, is one of the primordial elements. The destruction of lithium in young convective stars the ism contains lithium, 10% of which is primordial lithium created in the big bang and the other.
