Scientific paper

Secondary nucleosynthesis accompanying central He burning in massive stars (the site of the so-called 'weak' s-process component) is reinvestigated. A 'complete' set of stellar models (i.e., covering the whole mass range of massive stars) and the most recent nuclear data is used. For the first time, the production of secondary nuclei as a function of metallicity is investigated in detail, and a large range of initial stellar metallicities is explored; a thorough study of the various neutron sources and poisons reveals important effects at low metallicities, never analyzed in detail before. A comparison to solar system data is made, and yields of s-nuclei as a function of stellar mass and metallicity are given, for use in galactic chemical evolution models.
