Exoelectron emission

<p>In <a href="/facts/Atomic_physics/7Jlm4I7k">atomic physics</a>, exoelectron emission (EE) is a weak <a href="/facts/Electron_emission/gnBWwd7h">electron emission</a>, appearing only from pretreated (<a href="/facts/Irradiated/fHW0QNAa">irradiated</a>, deformed etc.) objects. The pretreatment ("<a href="/facts/Electron_excitation/66pkjfmB">excitation</a>") turns the objects into an unequilibrial state. EE accompanies the relaxation of these unequilibria. The relaxation can be stimulated e.g. by slight <a href="/facts/Heating/GsYBDLmn">heating</a> or <a href="/facts/Longwave/w4flmdvu">longwave</a> illumination, not causing emission from untreated samples. Accordingly, thermo- and  photostimulated EE (TSEE, PSEE) are distinguished. Thus, EE is an <a href="/facts/Electron/L0KBo5cW">electron</a> emission analogue of such optical phenomena as <a href="/facts/Phosphorescence/WshJFsKV">phosphorescence</a>, thermo- and <a href="/facts/Photostimulated_luminescence/CJUnTwhP">photostimulated luminescence</a>.
