Total and subshell-selective charge exchange cross sections and the corresponding reaction rate coefficients for Neq+-H (q=6–10) collision systems are calculated by utilizing the two-center atomic orbital close-coupling (TC-AOCC) method at impact energy between 0.1 keV/u and 500 keV/u. Good agreements with the experimental and other theoretical results are found for the total charge transfer cross section in the considered energy range and for those of the dominant charge-exchange channels for the higher collision energies. These charge exchange cross section data are useful for understanding and modeling the X-ray emission in environments where charge transfer is an important mechanism generating this emission.

高电荷 Ne 离子与原子氢碰撞中的总和亚壳层选择性电荷交换截面

Ne的总和亚壳选择性电荷交换截面和相应的反应速率系数q+-H (q=6–10) 碰撞系统是通过利用两中心原子轨道紧密耦合 (TC-AOCC) 方法在 0.1 keV/u 和 500 keV/u 之间的冲击能量下计算的。对于所考虑的能量范围内的总电荷转移横截面和较高碰撞能量的主要电荷交换通道的总电荷转移横截面,发现与实验和其他理论结果有很好的一致性。这些电荷交换截面数据对于理解和模拟在电荷转移是产生这种发射的重要机制的环境中的 X 射线发射非常有用。
