Scientific paper

The abundances of chemical elements in nine K supergiants in the SMC were investigated by the method of model atmospheres. With this goal high-resolution CCD-spectrograms were used. It is shown that all stars have a deficit of iron from -0.40 to -0.97 dex. relative to the Sun. Some differences in the abundances of the elements of alpha- (Si, Ca, Ti), s- (Y, Zr) and e- (Sc, V, Cr, Ni, Mn) processes relatively to iron abundance were found in the atmospheres of stars in the SMC and in our Galaxy.
