Scientific paper

Using data on carbonaceous chondrites of type CII, it is shown that the surface term, the Coulomb term, the symmetry of nuclear forces term and the pairing of nuclear forces term (all terms of the Weizacker-Bethe formula for binding energies) are related to solar system abundances of the nuclides beyond about A = 60-70. It is pointed out that there is an intrinsic consistency in the abundance distribution of the heavy elements which cannot be explained by the BBFH cosmology, in which the abundance distribution results from a mixture of products from several independent unrelated sources. This consistency implies, to the contrary, a common history of these nuclides during nucleosynthesis, or at least during its ultimate phase.
