Abstract
The decomposition of Ba, Nd, and Sm isotopic anomalies in the Allende meteorite into s-process and r-process enrichment is computed with experimental cross section data for all of the stable isotopes involved. The uncertainties in this decomposition are analyzed. It is concluded that these data may reveal a previously unobserved systematic system enirchment relative to solar system r-process material which favors the population of the lighter isotopes of each element. Some possible explanations for these systematics are discussed.
