 Core-excited shape resonance

Core-excited shape resonance is a phenomenon observed in the field of quantum mechanics and atomic physics, particularly in the context of electron scattering and the interaction of charged particles with matter. Here’s a summary of the key concepts involved: 1. **Shape Resonance**: This term generally refers to a type of resonance that occurs when an incoming particle experiences a potential barrier and the shape of the potential allows for the temporary trapping of the particle, leading to an enhancement of scattering processes.
