Widdekind Posted May 31, 2011 Share Posted May 31, 2011 According to this site, given the observed abundances of Deuterium, 3-Helium, & Lithium, Primeval Nucleosynthesis could have occurred, at almost any temperature, T < 500 MK, with next-to-no discriminative sensitivity beyond that. What is the cosmic abundance of neutrons (which would discriminate) ?? Link to comment Share on other sites More sharing options...
swansont Posted May 31, 2011 Share Posted May 31, 2011 I don't see where the website makes that claim. That's not what the graph is telling you. Link to comment Share on other sites More sharing options...

What is the cosmic abundance of neutrons (which would discriminate) ?? The nucleosynthesis occurred for T > 500 MK (NOT <). The cosmic abundance of FREE neutrons is 0.
