本文用GRASP 2K程序计算了镅电偶极跃迁K、L和M射线的跃迁能和跃迁率。考虑了Breit相互作用、真空极化和自能的影响。计算结果与其它实验值和理论值的符合率在0.04%以内。此外，我们还首次计算了电荷态为Am~（1+）-Am~（6+）的镅离子的K-、L-和M-壳层空穴态的跃迁能和跃迁速率。计算结果表明，最外层电子对内壳层跃迁性质的影响很小.
Transition energies and rates of K, L, and M X-ray lines from electric-dipole transition of americium have been calculated using GRASP2K code based on the Dirac-Hartee-Fock method. The effects of the Breit interaction, vacuum polarization and self energy were taken into account. It is found that the present results agree within 0.04% with other experimental and theoretical values. Furthermore, we also calculated transition energies and rates of the K-, L-, and M-shell hole states of americium ions with charge states Am~(1+)-Am~(6+) for the first time. It is found that the transition energies and rates change slightly relative to the corresponding results of americium atoms, which indicates that the outermost electrons can hardly affect inner-shell transition properties.
