一氧化碳的电子碰撞共振激发截面和速率系数

Electron--impact resonant vibration excitation cross sections and rate coefficients for carbon monoxide

V. Laporta, C. M. Cassidy, J. Tennyson, R. Celiberto

摘要:

在0-10 eV能量范围内,计算了CO分子81个振动态的共振振动和转动-振动激发截面,并假定激发是通过2 π共振进行的.使用R-矩阵方法进行的静态交换加极化计算用于估计作为核间分离的函数的共振位置和宽度。核运动的影响被认为是使用本地复势模型。从振动基态激发的实验数据得到了很好的一致性。激发速率和截面作为初始CO振动态的函数提供给所有的基态振动能级。

英文摘要:

Resonant vibrational and rotation-vibration excitation cross sections for electron-CO scattering are calculated in the 0-10 eV energy range for all 81 vibrational states of CO, assuming that the excitation occur via the 2Π shape resonance. Static exchange plus polarization calculations performed using the R-matrix method are used to estimate resonance positions and widths as functions of internuclear separation. The effects of nuclear motion are considered using a local complex potential model. Good agreement is obtained with available experimental data on excitation from the vibrational ground state. Excitation rates and cross sections are provided as a functions of the initial CO vibrational state for all ground state vibrational levels.
