11Electron spectroscopy — is an analytical technique to study the electronic structure and its dynamics in atoms and molecules. In general an excitation source such as x rays, electrons, or synchrotron radiation will eject an electron from an inner shell orbital of an… …
12Electron configuration — Electron atomic and molecular orbitals Simp …
13Electron density — is the measure of the probability of an electron being present at a specific location. In molecules, regions of electron density are usually found around the atom, and its bonds. In de localized or conjugated systems, such as phenol, benzene and… …
14Electron capture — (sometimes called inverse beta decay) is a decay mode for isotopes that will occur when there are too many protons in the nucleus of an atom and insufficient energy to emit a positron; however, it continues to be a viable decay mode for… …
15Electron beam ion trap — (or its acronym EBIT) is used in physics to denote an electromagnetic bottle that produces and confines highly charged ions. It was invented by R. Marrs [Levine et al, 1988] and M. Levine at LLNL.An EBIT uses an electron beam focused by means of… …
16Electron beam processing — involves irradiation of products using a high energy electron beam accelerator. Electron beam accelerators utilize an on off technology, with a common design being similar to that of a cathode ray television.Electron beam processing is used in… …
17Electron therapy — or Electron Beam Therapy (EBT) is a kind of external beam radiotherapy where electrons are directed to a tumor site.IndicationsElectron beam therapy is used in the treatment of superficial tumors and it may also be used to boost the radiation… …
18Electron binding energy — (BE) is the energy required to release an electron from its atomic or molecular orbital. Binding energy values are normally reported as positive values with units of eV . The binding energies of 1 s electrons are roughly proportional to (Z 1)²… …
19electron gun — n. the part of an electron tube, esp. a cathode ray tube, that emits, accelerates, and controls a beam of electrons …
20electron microscope — n. an instrument that focuses a beam of electrons on an object, using electric or magnetic fields, to form an enlarged image of the object on a fluorescent screen, photographic plate, or cathode ray tube; specif., such an instrument in which the… …
