摘　　要：对原子簇P_4,As_4,Sb_4,Sb_4^(2-)和Bi_4^(2-)中磷、砷、锑和铋原子的nd轨道参予成键作用进行了研究.通过对体系能量和在形成化学键的两原子间找到键子的几率的计算表明,磷、砷、锑和铋原子的nd轨道对这些原子簇中键的形成起着重要的作用.The participation of the nd orbitals of P, As, Sb and Bi atoms in the bond fotmation in the four-atom clusters P4, As4, Sb4, Sb4-and Bi4-was investigated. It was indicated, by calculations on the probabilities for finding bonding electrons between two atoms forming a chemical bond and on energise of these systems, that the nd orbitals of the P,As,Sb and Bi atoms played an important role in the bond formation in the four-atom clusters.
