摘要

。我们研究了涉及氢、锂和钠分子阳离子的电子碰撞过程。本文报道了主量子数n≥4、温度在500 ~ 10000 K范围内解离复合的速率系数。所考虑的碰撞过程对电离能级和原子激发态居群以及光学特性都有影响。这些数据对早期宇宙动力学的建模和地球等离子体的研究是有用的。

Electron-impact processes involving small molecular ions relevant for the astrochemistry

. We investigated the electron-impact processes involving hydrogen, lithium and sodium molecular cations. Rate coeﬃcients for the dissociative recombination in domains of principal quantum numbers n ≥ 4 and temperatures from 500 K to 10 000K are reported. Considered collisional processes have an impact on the ionization level and atom excited-state populations as well on optical characteristics. The data are useful for the modeling of the kinetics of the Early Universe and for geocosmical plasma investigation.
