Y and Ba in open clusters
Basing on the VLT high resolution spectra of stars of five open clusters Ruprecht 4, Ruprecht 7, Berkeley 25, Berkeley 73 and Berkeley 75 (Carraro et al., 2007) we determined the abundance of yttrium and barium by the method of synthetic spectrum. The calculation of the barium abundance is carried out in the approximation of non-LTE. We analyzed the behavior of yttrium and barium with the age of open clusters and stars of the Galactic thin disk.
