WebIn atomic physics, the effective nuclear charge is the actual amount of positive charge experienced by an electron in a multi-electron atom. The term "effective" is used because the shielding effect of negatively charged electrons prevent higher energy electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner layer. WebMar 7, 2024 · Nonadiabatic Born effective charges in metals and the Drude weight. Cyrus E. Dreyer, Sinisa Coh, Massimiliano Stengel.
