Zero-Energy Resonance Effects in Break-up Collisions
Conference paper
Abstract
We show that the analysis of cusp and threshold structures in breakup collisions of nuclei, atoms and molecules represents an alternative approach for the study of elastic two-particles collisions at extremely low-energies. We illustrate these general ideas by showing that the “electron capture to the continuum” cusp in the ionization of atoms by neutral projectiles can be understood in terms of a resonance mechanism. This approach allows for the extraction of the s-wave scattering length for the electron-projectile interaction.
