摘要：Abundances of neutron-capture elements are calculated in the atmospheres of three metal-poor stars and the standard star Arcturus with a special emphasis to niobium. The method of spectral synthesis, carefully compiled line lists and recent data of hyperfine splitting for Nb I lines are used. The results and possible origin of niobium in the analyzed metal-poor stars are discussed.
