In the present study rate coefficients for vibrational excitation of CO_{2} gas molecules by electrons in the presence of uniform electric and magnetic fields are investigated. Calculations are performed for transition from the ground state to each of the symmetric, asymmetric, and bending vibrational states. A Monte Carlo simulation is used to produce nonequilibrium electron energy distribution functions. Results are obtained for the electric field over gas number density ratio, E/N, ranging from 20 to 1000 Td, and for the magnetic field over gas number density ratio, B/N, with values of 0, 1000, 2000, and 3000 Hx.
在本研究中,对均匀电场和磁场存在下电子激发CO₂气体分子振动的速率系数进行了研究。针对从基态到对称、非对称和弯曲振动状态的每一种跃迁进行了计算。采用蒙特卡罗模拟来生成非平衡电子能量分布函数。得到了气体数密度比E/N范围为20至1000 Td,以及气体数密度比B/N值为0、1000、2000和3000 Hx时的结果。
