Hi, In "Nuclear Physics of stars" by Christian Iliadis, the author calculates that the D/H equilibrium ratio is about 1E-18 to 1E-17 depending on temperature. He also quotes a figure of 3E-5 for the ratio in the primordial gasses of the universe. Both are much smaller than the ratio in water which is about 1.5E-4, so one is left wondering how water became so enriched in D.
Is it possible that there is an unknown CF mechanism at work in the universe creating extra D? ;) (or perhaps lots of D is created during the collapse of giant stars prior to exploding as a super nova). Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
