Scientific paper
New calculations of s-processing in TP-AGB stars of low mass based on an updated compilation of neutron capture cross sections are presented. It is shown how the reproduction of solar abundances for the s-isotopes of Ba requires a special choice of neutron capture cross sections of Ba-136 and Ba-138. It is further shown how agreement between the predictions of He shell nucleosynthesis and the Ba isotopic mixture of the G-component in SiC can be obtained, once C-stars with mean neutron exposures lower than that required to fit the solar main component are considered. Problems related to the interpretation of other isotope anomalies in SiC are also examined.
