Basic physical and chemical processes induced by attachment of free electrons to molecules or an atoms were measured. The molecules and atoms are chosen by relevance to plasma processing, nanofabrication by focused electron beams, atmospheric and space chemistry, radiation damage to living tissue, fusion plasma, and by pure scientific interest. The latter concerns particularly new resonant phenomena near threshold and in the backward scattering, in scattering with complex molecules, and in collaborations with current development of scattering theory. Emphasis is on advanced custom-built instrumentation, permitting the measurement of high-quality quantitative (absolute) cross sections for elastic scattering, vibrational and electronic excitation, and dissociative electron attachment. Exploratory measurements of electron collisions with ionic liquids and dissolved molecules were performed. The technique od 2-dimensional Electron Energy Loss Spectroscopy has been introduced as a means to gain insight into the ultrafast (order of 1ps) nuclear dynamics on resonant potential surfaces of a transient anion.
