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
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

Emission spectrum — The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element s atoms or the compound s molecules when they are returned to a lower energy state. Each element s … Wikipedia
Gamma spectroscopy — The gamma ray spectrum of natural uranium, showing about a dozen discrete lines superimposed on a smooth continuum, allows the identification the nuclides 226Ra, 214Pb, and 214Bi of the uranium decay chain. Gamma ray spectroscopy is the… … Wikipedia
Nuclear shell model — In nuclear physics and nuclear chemistry, the nuclear shell model is a model of the atomic nucleus which uses the Pauli exclusion principle to describe the structure of the nucleus in terms of energy levels.[1] The first shell model was proposed… … Wikipedia
Mössbauer effect — The Mössbauer effect, or recoilless nuclear resonance fluorescence, is a physical phenomenon discovered by Rudolf Mössbauer in 1958. It involves the resonant and recoil free emission and absorption of γ radiation by atomic nuclei bound in a… … Wikipedia
