Resonance and Threshold Phenomena in Low-Energy Electron Collisions with Molecules and Clusters

摘要: Publisher Summary This chapter discusses resonance and threshold phenomena in low-energy electron collisions with molecules clusters. Low-energy of electrons atoms are among the most important elementary processes gaseous environments such as discharges, arcs, gas lasers, dielectrics earth's atmosphere. The dynamics behavior electron-molecule is discussed. dynamical slow traversing gases to a large extent determined by two effects: energy dependent evolution scattering phases for relevant partial waves influence temporary negative ion states (resonances). Some aspects theoretical description generally requires an adequate electronic, vibrational rotational degrees freedom. However, if typical collision time short compared period, molecule can be treated having fixed orientation during process, result cross-section averaged over orientations. Treatment usually more challenging theory. In region applications, many inelastic excitation dissociative attachment driven negative-ion resonances. these cases based on nonlocal complex potential describing nuclear motion intermediate state.
