Primordial NucleosynthesisThe Universe was created about 15 billion years back by gradual expansionfrom a state of extremely high density (ρ~10 95 g/cc) & temperature (T~ 10 32 K) Big Bang Theory.Nucleosynthesis could start ~ 3 minutes after the Big Bang when Deutorium(B.E. 2.23 MeV) stable against photo-dissociation at T ~ 10 9 K.Nucleosynthesis could continue for a very shorttime after the big-bang because :• All neutrons were used up for production of 4 He• No stable nuclei for A=5 and A=8• Baryon density too low for 3 body reactions• Temp. reduced due to expansion to sustainfurther nuclear reaction1H2H3He4He6Li7LiMass Fraction0.75(2.5±1.5)x10-5(4.2±2.8)x10-50.23±0.023004600+ 300 −12× 10− 150+ 4600 −12× 10− 2300
