Abstract

The charge transfer in a nonadiabatic spin–orbit induced process N(⁴S) + H

^{+}

\to

^{+}

(³P) + H(²S) is investigated. The cross section and the rate constant are reported and compared with other calculations, correcting the previous values based on approximate potentials.

The calculation is extended to collisions involving deuterium and tritium, which are relevant for the transport codes (such as SOLPS-ITER) used in the modeling of fusion plasma.

The method used is a combination of the Landau–Zener theory with a novel methodology based on one-dimensional Gaussian wavepacket propagation.

H+/D+/T+-N（4S）碰撞中自旋轨道诱导电荷转移

研究了非绝热自旋轨道诱导过程N(4S) + H+→N+(3P) + H（2S）中的电荷转移。报告了横截面和速率常数，并与其他计算进行了比较，修正了基于近似电位的先前值。计算扩展到涉及氘和氚的碰撞，这与用于聚变等离子体建模的传输代码（如SOLPS-ITER）有关。该方法结合了朗道-齐纳理论和一种基于一维高斯波包传播的新方法。
