Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis. After about 20 minutes, … See more Timeline It is thought that the primordial nucleons themselves were formed from the quark–gluon plasma around 13.8 billion years ago during the Big Bang as it cooled below two trillion … See more Theories of nucleosynthesis are tested by calculating isotope abundances and comparing those results with observed abundances. Isotope abundances are typically calculated from the transition rates between isotopes in a network. Often these calculations … See more Tiny amounts of certain nuclides are produced on Earth by artificial means.

Chrome Extension Upload PDF Discover The creation of light elements during BBN was dependent on a number of parameters; among those was the neutron–proton ratio (calculable from Standard Model physics) and the baryon-photon ratio. The neutron–proton ratio was set by Standard Model physics before the nucleosynthesis era, essentially within the first 1-second after the Big Bang.

Fusion continued in the Era of Nucleosynthesis (0.001 seconds – 3 minutes), when protons and neutrons combined into the first atomic nuclei, hydrogen, some of which fused further into helium and lithium. Furthermore, what happened during the gut era?

WebFeb 1, 2024 · Big Bang nucleosynthesis occurred in the presence of copious amounts of free neutrons, produced in collisions between high-energy protons and electrons when the Universe was at a temperature of 10 billion K ( 5 ). When the temperature of the Universe fell to 1 billion K, those free neutrons fused easily with protons to make deuterium ( 2 H). WebWe explore the effect of neutron lifetime and its uncertainty on standard big bang nucleosynthesis (BBN). BBN describes the cosmic production of the light nuclides, 1H, D, 3H+3He, 4He, and 7Li+7Be, in the first minutes of cosmic time.
