s-process nucleosynthesis of 142^Nd: crisis of the classical model
C. Arlandini, F. Kaeppeler, K. Wisshak +4
The recently improved information on the stellar neutron capture cross sections of neutron magic nuclei at N = 82, and in particular for 142^Nd, turned out to represent a sensitive…

A New Astrophysical Interpretation of the Si and Ti Isotopic Compositions of Mainstream SiC Grains from Primitive Meteorites
Maria Lugaro, Roberto Gallino, Maurizio Busso +2
Mainstream presolar SiC grains from primitive meteorites show a clear s-process signature in the isotopic composition of heavy trace elements. These grains most likely condensed in…

Galactic chemical evolution of Ba-peak elements
C. Travaglio, D. Galli, R. Gallino +3
The chemical evolution of the Galaxy is followed for the elements affected by neutron capture, in particular for those in the atomic number range 56 to 63 (Ba, La, Ce, Pr, Nd, Sm a…
