| 摘 要： | 用代数能量方法得到了Li2分子9个电子态的振动光谱常数，完全振动能谱{Ev}和分子离解能De．结果显示：振动能谱{Ev}不仅能重复有限的已知实验数据，而且能给出一些未知的高阶振动能量．用AEM所得到的离解能很好的符合了已知的实验值De．对一些双原子系统，当无法得到实验离解能时，用AEM方法也能得到合理的近似离解能值．

| Abstract: | The vibrational spectroscopic constants,full vibrational energy spectra {Ev},and molecular dissociation energies De,for nine electronic states of Li2 molecule are obtained using algebraic energy method(AEM).The results show that the generated vibrational energy spectrum {Ev } not only reproduces limited known experimental data but also correctly gives all unknown high-lying vibrational energies.The AEM dissociation energy excellently agrees with known experimental De,and the AEM can generate reasonable appr... |
