摘　　要：本文用多重散射波(X_α-SW)法对含3d族过渡金属杂质的六角密积(hcp)结构原子簇Al_2M(M为Cr,Mn,Fe,Co和Ni)的电子结构作自洽计算。结果表明,杂质的存在对体系的费密能级附近的电子态有重要的影响。体系的一些重要性质,如电离势并非随杂质原子序的变化作单调变化。Xα-SW SCF calculations have been carried out for hep structure cluster Al12M, where M is one of 3d transition metal impurity atoms Cr, Mn, Fe, Co and Ni. The calculated results indicate that the electronic structures near the Fermi levels are notably influenced by the impuriy atoms. With the variation of impurity atomic numbers the ionization potentials of the systems vary not monotonously.
