We will use two state of the art crossed beam spectrometers to measure absolute differential and integral cross sections for low energy electron scattering from molecules and their molecular fragments (radicals). The species to be considered are those of significant industrial (e.g. C2F4, C4F8 and CF2) and environmental (e.g. CO2 and H2O) interest, with the cross sections we will measure being crucial to our modelling both the processes involved in plasma enhanced chemical vapour desposition of semiconductor devices and the spectral emission characteristics of planetary atmospheres. The modelling will be conducted self-consistently with our enhanced statistical equilibrium simulation code, which is unique to Australia.

我们将使用两个国家的最先进的交叉束光谱仪来测量绝对微分和积分截面的低能电子散射分子及其分子碎片（自由基）。 要考虑的物种是那些重要的工业（如C2F4，C4F8和CF2）和环境（如CO2和H2O）的利益，与横截面，我们将测量是至关重要的，我们的建模过程中所涉及的等离子体增强化学气相沉积的半导体器件和行星大气的光谱发射特性。 该模型将进行自我一致的增强统计平衡模拟代码，这是澳大利亚独有的。
