Chasing Escaping Electrons: Time-Resolved ICD and the Prospect of Measuring ICEC

Interparticle Coulombic Decay and Interparticle Coulombic Electron Capture are general and efficient environment assisted processes, in which energy is transferred from one unit to another due to electron correlation and results in the emission of a slow electron. They are relevant to biological systems, astrophysics and nanotechnology.

In ICD, an innervalent vacancy is filled by an electron of the same unit while transferring the excess energy to a different unit which consequently emits an electron.

I will question the meaningfulness of the lifetime of this family of processes when measured in a time-resolved manner and report, how the decay width can be extracted reliably instead.

ICEC is characterized by an electron capture triggering an energy transfer and resulting in the ionization of a neighboring unit. While ICD is well established in the scientific community, ICEC has not been measured yet. I will therefore report on the newest theoretical results in the impact of nuclear motion and give a perspective for future measurements.
