Spectroscopic study of barium stars. III. Chemical composition of HD 46407, HD 65854, HD 101013, HD 104979, HD 139195, HD 205011.
Using spectrograms with a dispersion of 14 Å/mm in the red spectral band (λ5300 - 6700 Å) six Ba II stars are analyzed by the model atmosphere method. The values of effective temperatures, surface gravity, microturbulent velocity and the abundance of 20 elements from Li to Eu were determined.
