变价稀土元素L,M,N内壳层电子束缚能量的变化

变价稀土元素的4f电子占有数可以随不同的温度、压力或者组成(为化合物时)而作“连续”或不连续的变化,对于不同的4f电子占有数,其内壳层电子的束缚能量也将有所不同,本文应用相对论性原子自洽场理论计算由“变价”而引起的束缚能移动。 关键词：

VARIATION IN L, M, N INNER-SHELL ELECTRON BINDING ENERGIES OF RARE-EARTH ELEMENTS IN VALENCE TRANSITION

In the valence transition phenomena, the occupation number of the 4f electrons of the rate-earth atoms will change "continuously" or discontinuously under the condition of different temperatures, different pressures or different compositions (as chemical compounds). Owing to the different occupation number of the 4f electrons, the binding energies of the inner-shell electrons of the rare-earth atoms will vary. We, here, apply a relativistic Dirac-Slater self-consistent field method to calculate the variation of the inner electron binding energies due to valence transition.
