Resonances and Threshold Effects
Abstract Much of the energy-dependent structure observed in low-energy electron scattering arises from resonances and threshold effects. Resonances are due to nearly bound states of the (N + 1)-electron system of target atom and external electron. In a time-dependent formalism, such a state decays with a finite lifetime if it interacts with states in an electron scattering continuum. The uncertainty principle implies a corresponding energy width. Cross sections in the interacting continuum are modified within the energy range defined by the resonance energy and width.
