In article , Sam Wormley writes: No, most He, Li came out of the big bang. You sure about lithium, Sam? I thought most of it came from spallation with only a negligible amount produced in the BB. The "mass 5 barrier" is hard to overcome. No, I am not, Steve. The WMAP data indicates the the Lithium at the time of decoupling Li is less that 1 part in 10^9 compared to H. When I made the post I was mistakenly thinking 1 part in 10^6 as apposed to about 1 part in 10^10. Ref: http://map.gsfc.nasa.gov/media/101087/101087b.png Thank you Steve, I stand corrected. |
