multi-electron excitation theory

Multi-electron excitation theory describes how, when an atom absorbs energy, multiple electrons can be simultaneously excited to higher energy levels rather than just one. This process involves complex interactions among electrons within the atom, accounting for their mutual repulsions and correlations. It provides a more accurate picture of an atom’s behavior under intense energy conditions, such as in high-energy collisions or strong electromagnetic fields, helping scientists better understand atomic structure and spectral properties by considering the collective excitation effects of multiple electrons.
