Production of 92 Nb, 92 Mo, and 146 Sm in the g-process in SNIa

Sm provide constraints for GCE and production sites but are still prone to nuclear uncer-tainties as only few of the important reactions are experimentally determined. We present calcu-lations for a single-degenerate Chandrasekhar-mass SNIa model [3], in which material is accretedfrom a companion AGB star and enriched in s-process seeds before the explosion of the WhiteDwarf. The temperature and density history of a mass element is followed through the explosionby using tracers. We scrutinize specific tracers with maximal production of
