  The solar s-process abundances have been analyzed in the framework of a
Galactic Chemical Evolution (GCE) model. The aim of this work is to implement
the study by Bisterzo et al. (2014), who investigated the effect of one of the
major uncertainties of asymptotic giant branch (AGB) yields, the internal
structure of the 13C pocket. We present GCE predictions of s-process elements
computed with additional tests in the light of the suggestions provided in
recent publications.
  The analysis is extended to different metallicities, by comparing GCE results
and updated spectroscopic observations of unevolved field stars. We verify that
the GCE predictions obtained with different tests may represent, on average,
the evolution of selected neutron-capture elements in the Galaxy. The impact of
an additional weak s-process contribution from fast-rotating massive stars is
also explored.
