摘要: 在YH-1/YH-2计算机上将多重散射Xα自洽场方法(SCF-Xα-SW)程序和线性Mufin-tin轨道方法(LMTO)程序做了改进,实现了向量化和并行化。研究了C60的能级;计算了苯分子从1e1g,2e2g和1a2u开始激发的108个Rydberg态单电子轨道激发能,即1e1g,2e2g,1a2uka1g(k=3-11),ke2g(k=2-7),ke1u(k=3-8),ke1g(k=2-5),ke2g(k=3-5),ke2u(k=2-3),kb2u(k=2-3),kb1u(k=2-3),1b1g,1b2g;还研究了铀铌合金的电子结构及体模量。

Abstract: Some improving works have been done on the SCF-Xα-SW and LMTO Programs by vectorization and parallelization.The energy level of C60 is researched.The 108 one electrom Rydberg excitation energies of benzene,such as 1e1g,2e2g,1a2uka1g(k=3-11),ke2g(k=2-7),ke1u(k=3-8),ke1g(k=2-5),ke2g(k=3-5),ke2u(k=2-3),kb2u(k=2-3),kb1u(k=2-3),1b1g,1b2g are calculated.The electronic structure and bulk modulus of some U-Ni alloys are also analyzed.

Key words: C60, Benzene Rydberg state, U-Ni alloys
