Description

It is shown that according to the standard hot-big-bang nucleosynthesis calculations, no single value of the ratio eta of baryon to the photon number density can explain the right abundances of both 4He and 2D. A slight neutrino degeneracy, however, provides a testable solution for eta which is in conformity with the current estimate of the baryonic component of the density parameter (Ω/sub N/)0 of the Universe
