摘要

基于高质量的电子结构势曲线和耦合，计算了涉及基态氮原子N（4S）和第一激发态氮原子N（2D）的碰撞的微分截面、积分截面和输运截面。同样的数据集的励磁交换截面也计算。用量子散射方法计算了基态原子碰撞时的激发速率常数和基态原子与激发态原子碰撞时的猝灭速率常数，并与Landau-Zener和Zhu-Nakamura半经典方法的结果进行了比较。

Elastic cross sections, excitation exchange cross sections, and rate constants for excitation and quenching in N(4S)-N(2D) collisions

Differential, integrated, and transport cross sections were calculated for collisions involving ground state nitrogen atoms N(⁴S) and first excited state N(²D) nitrogen atoms, based on high quality electronic structure potential curves and couplings. The same data set for the excitation exchange cross section was also calculated.

The rate constant for excitation in collisions of ground state atoms and the rate constant for quenching (reverse process) in collisions between ground and excited atoms were calculated using a quantum scattering method and compared with the results of the Landau–Zener and Zhu–Nakamura semiclassical methods.
