Core level photoemission

Core level photoemission is a technique used to study the electronic structure of materials. When high-energy light strikes a sample, it can eject electrons from the deep, inner electron shells called core levels. By measuring the energy of these ejected electrons, scientists can identify the elements present and gain insights into their chemical environment and bonding. This method helps in understanding material properties at the atomic level, providing valuable information for fields like materials science, chemistry, and physics.
