讨论了类氢铀离子与H₂分子碰撞中,经KLL共振转移和激发过程形成类氦铀离子双电子激发态的机制,分析了实验测量到的X射线能谱和各种竞争过程对X射线能谱的贡献.对由于纯电子-电子相互作用形成的双激发态的Kα辐射衰变的超级卫星线的角分布测量结果表明,角分布呈各向异性,电子态布居存在很强的定向排列.

The Mechanism of formation of the doubly excited states in collisions between H-like Uranium and H₂ via resonant transfer and excitation process was reviewed, and compared with radiative electron capture. The contributions from competing processes in the measured X-ray spectrum are discussed. From the measured angular distribution for the Kα hyper-satellite, it is found that strong anisotropy exists for the resonance KL_1/2L_3/2, in contrast to the resonance KL_3/2L_3/2, the difference may be due to the Pauli exclusion principle and jj-couplings of the electron-electron interaction.
