Scientific paper

A detailed abundance analysis of 13 rare-earth elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Tm, Yb, and Lu) has been carried out relative to the Sun for the bright F star Procyon (F5 IV - V). Weak and broadened rare-earth lines were analyzed by the method of spectrum synthesis. It was found that Procyon closely resembles the Sun in its rare-earth composition.
