  The MINCE (Measuring at Intermediate metallicity Neutron-Capture Elements)
project aims to gather the abundances of neutron-capture elements but also of
light elements and iron peak elements in a large sample of giant stars in this
metallicity range. T The aim of this work is to study the chemical evolution of
galactic sub-components recently identified (i.e. Gaia Sausage Enceladus (GSE),
Sequoia). We used high signal-to-noise ratios, high-resolution spectra and
standard 1D LTE spectrum synthesis to determine the detailed abundances. We
could determine the abundances for up to 10 neutron-capture elements (Sr, Y,
Zr, Ba, La, Ce, Pr, Nd, Sm and Eu) in 33 stars. The general trends of abundance
ratios [n-capture element/Fe] versus [Fe/H] are in agreement with the results
found in the literature. When our sample is divided in sub-groups depending on
their kinematics, we found that the run of [Sr/Ba] vs [Ba/H] for the stars
belonging to the GSE accretion event shows a tight anti-correlation. The
results for the Sequoia stars, although based on a very limited sample, shows a
[Sr/Ba] systematically higher than the [Sr/Ba] found in the GSE stars at a
given [Ba/H] hinting at a different nucleosynthetic history. Stochastic
chemical evolution models have been computed to understand the evolution of the
GSE chemical composition of Sr and Ba. The first conclusions are that the GSE
chemical evolution is similar to the evolution of a dwarf galaxy with galactic
winds and inefficient star formation.
  Detailed abundances of neutron-capture elements have been measured in
high-resolution, high signal-to-noise spectra of intermediate metal-poor stars,
the metallicity range covered by the MINCE project. These abundances have been
compared to detailed stochastic models of galactic chemical evolution.
