Scientific paper

A spectrum synthesis code has been used to measure Be abundances for three halo stars and an upper limit for a fourth. The abundances are discussed considering models for Galactic and primordial synthesis of Be. Upper limits are placed on possible primordial nucleosynthesis. A new model for the evolution of Be abundances in the halo is computed using constraints imposed by its overall metallicity distribution. Observations of stars of (Fe/H) about -2.0 are required to clarify the enrichment history of this element.
