Документ Three giants – members of The Open cluster M 67(Одеський національний університет імені І. І. Мечникова, 2017) Mishenina, T. V.; Klochkova, V. G.; Panchuk, V.; Basak, N. Yu.; Kovtyukh, Valery V.; Korotin, S. A.; Velichko, A.We determined the atmospheric parameters and chemical composition of the three giants, which are members of the open cluster M 67. The high resolution spectra (R = 60 000) were obtained with the echelle spectrograph NES mounted on the 6-meter telescope of the SAO RAS Obtained variations in Na and Zr abundances are within the determination errors. The Li abundance suggest a depletion of Li in the course of stellar evolution. For studied giants, the iron abundances derived from the neutral and ionized iron lines have not shown any significant discrepancies. The [Ba/Fe] values are close to the solar ones.
