THREE GIANTS – MEMBERS OF THE OPEN CLUSTER M 67

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-metertelescope 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  ofstellar 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.
