Nuclear isomer — A nuclear isomer is a metastable state of an atomic nucleus caused by the excitation of one or more of its nucleons (protons or neutrons). Metastable refers to the fact that these excited states have half lives more than 100 to 1000 times the… … Wikipedia
Mössbauer spectroscopy — A Mössbauer absorption spectrum of 57Fe Mössbauer spectroscopy is a spectroscopic technique based on the Mössbauer effect. This effect, discovered by Rudolf Mössbauer in 1957, consists in the recoil free, resonant absorption and emission of gamma … Wikipedia
Mössbauer effect — Physics. the phenomenon in which an atom in a crystal undergoes no recoil when emitting a gamma ray, giving all the emitted energy to the gamma ray, resulting in a sharply defined wavelength. [1955 60; named after R. MÖSSBAUER] * * * ▪ physics… … Universalium
Electronegativity — This electrostatic potential map shows how the oxygen atom has a more negative charge than the hydrogen atoms. Electronegativity, symbol χ (the Greek letter chi), is a chemical property that describes the tendency of an atom or a functional group … Wikipedia
Isomerieverschiebung — Die Isomerieverschiebung ist ein physikalischer Effekt, der sich darin äußert, dass die Lagen der Spektrallinien in Atomspektren und Gammastrahlung unterschiedlicher Isomere eines chemischen Elements nicht identisch sind. Im Falle von… … Deutsch Wikipedia
