Processes of interaction of low-energy electrons with molecules play an important role in gaseous and plasma environments such as discharges, arcs, gas lasers, and gaseous dielectrics. Recent studies have revealed the importance of interactions of low-energy electrons with biological molecules (DNA and RNA bases) and molecules of environmental interest. The research isfocused on dissociative electron attachment to complex molecules where intermediate resonant electronic states play a critical role. The nonlocal complex potential theory and the resonant R-matrix theory will be applied to investigate the interaction of these states with the nuclear degrees of freedom to understand the dissociative process.

低能电子与分子的相互作用过程在气体和等离子体环境如放电、电弧、气体激光和气体放电中起着重要作用。 最近的研究揭示了低能电子与生物分子（DNA和RNA碱基）和环境分子相互作用的重要性。 研究的重点是解离电子附着到复杂的分子中，中间共振电子态起着至关重要的作用。 非定域复势理论和共振R矩阵理论将被用来研究这些态与核自由度的相互作用，以理解解离过程。
