Intermolecular Coulombic Electron Capture (ICEC) is an environment
assisted process in which a free electron can efficiently attach to a quantum system by transferring the excess energy of the electron capture to a neighbor ionizing it.
ICEC is expected to be a general process that controls damage of living
cells under ionizing irradiation. Furthermore, water being the solvent of life, it is therefore highly relevant to investigate ICEC in aqueous systems. The latter can thus reveal the potential impact of ICEC on radiation damage. In the last 5 years, our group has developed the methodology and numerical tools to investigate ICEC in various systems, ranging from rare gas dimers to micro-hydrated cations. More recently, we have focused our attention to ICEC in aqueous systems. In this talk, I will give an overview of our works and summarize our current knowledge of ICEC.
