Primordial Helium Abundance and the Primordial Fireball. II
Abstract
This paper contains results of a calculation of the He3, He', and deuterium abundances produced in the early stages of expansion of the Universe. It is assumed in the calculation that the present temperature of the primordial fireball is 3 K, and the abundances are computed for two values of the present mean density of matter in tbe Universe, and for a range of possible changes in the time scale for expansion of the early Universe.
