用管状同步辐射在Mo2p32/吸收边附近测量了MoL3M4.5M4.5俄歇电子能谱。研究发现，随着光子能量的增加，L3M44d.5M4.5俄歇线向更高的动能方向移动，Mo约为4 eV，Li2MoO4约为12 eV。研究还表明，Li2MoO4的L3M4.5M4.5俄歇谱线在Mo2p3/2到4d(5s)共振激发的正上方分裂成双峰结构，分别称为旁观俄歇跃迁和正常俄歇跃迁。用入射光子的俄歇共振拉曼散射和绝缘固体中空位分子轨道的带状结构解释了Li2MoO4情况下的特性。
The Mo L3M4.5M4.5 Auger electron spectra have been measured with tubbable synchrotron radiation in the vicinity of the Mo 2p32/ absorption edge. It has been found that the L3M44d.5M4.5 Auger lines shift to a higher kinetic energy with increasing photon energy, about 4 eV for Mo and about 12 eV for Li2MoO4. It is also shown that the L3M4.5M4.5 Auger lines of Li2MoO4 are split into two-peak structures just above the resonant Mo 2p3/2 to 4d(5s) excitation, which are assigned as the spectator and normal Auger transitions. The peculiarities in the Li2MoO4 case are interpreted in terms of the Auger resonant Raman scattering of the incident photons and band-like structures of the unoccupied molecular orbitals in the insulating solid.
