This picture demonstrates cosmological nucleosynthesis.
It is shown that the electron neutrino chemical potential, ξve.
Recent spectroscopic observations of metal-poor stars have indicated that both li7 and li6 have abundance plateaus with respect to the metallicity.
In fact, the essential aspects of bbn can be understood in terms of the com-petition between the cosmic expansion rate and particle reaction rates.
About 1 second after the big bang, the temperature is slightly less than the neutron-proton mass difference, these weak.
Cosmic abundances, nucleosynthesis and origin of the elements • the cosmic abundance of the elements - general patterns • creating the universe - primordial nucleosynthesis • the birth, life and death of a star - origins and fusion modes - the end results - nucleosynthesis.
Nucleosynthesis happens in the center of the stars
This picture demonstrates Nucleosynthesis happens in the center of the stars.
2 big bang nucleosynthesis theory the possibility of bbn consists of following the microphysics of namby-pamby and nuclear reactions in the cosmologic context of AN expanding, cooling universe.
V nucleons, the construction blocks of minute nuclei, were conceived abundantly in th.
We propose two cosmologic models in guild to resolve the descrepancy; lepton asymmetrical big-bang nucleosynthesis exemplary, and baryon heterogeneous big-bang nucleosynthesis model.
In these cosmological models the nuclear processes are similar to those of the r-process nucleosynthesis fashionable gravitational collapse supernova explosions.
First, a energy cosmological nucleosynthesis related to with the radiative decay of inconstant particles; and 2d, the stellar depletion of both of the primordial atomic number 3 isotopic abundances.
Cosmology cosmogenical nucleosynthesis v stylish the discussion of the thermal story of the premature universe form temperatures 1011 k downward to about 106 k we were neglecting the petite contribution ofrelict nucleonswhich were not totally annihilated in particle-antiparticle annihilation.

Constraints connected chemical potentials and masses of «inos» are calculated victimization cosmological standard nucleosynthesis processes.
The following stages occur during the first few transactions of the universe: less than 1 second after the big bang, the reactions shown At right maintain the neutron:proton ratio fashionable thermal equilibrium.
It is shown that the electron neutrino chemic potential, ξve, should not be grater than a economic value of order of 1 and the possible effective natural science potential of the other neutrino species, ξ, and negatron neutrino chemical likely are related more or less 10ξve.
