excited state — noun : any of the states of a physical system (as of atoms, molecules, atomic nuclei) that is higher in energy than the ground state * * * Physics. any of the energy levels of a physical system, esp. an atom, molecule, etc., that has higher… … Useful english dictionary
radiation measurement — ▪ technology Introduction technique for detecting the intensity and characteristics of ionizing radiation, such as alpha, beta, and gamma rays or neutrons, for the purpose of measurement. The term ionizing radiation refers to those… … Universalium
nuclear fission — fission (def. 2). [1885 90] * * * Division of a heavy atomic nucleus into two fragments of roughly equal mass, accompanied by the release of a large amount of energy, the binding energy of the subatomic particles. The energy released in the… … Universalium

Nuclear laser — Not to be confused with Nuclear pumped laser. A nuclear laser is a laser that would depend on the excitation of atomic nuclei to produce electromagnetic radiation.No such laser exists yet as of April 2011. Eugene Tkalya of Moscow State University … Wikipedia
Giant resonance — is a high frequency collective excitation of atomic nuclei, as a property of many body quantum systems. In the macroscopic interpretation of such an excitation in terms of an oscillation, the most prominent giant resonance is a collective… … Wikipedia
metastable state — Excited state (see excitation) of an atom, nucleus, or other system that has a longer lifetime than the ordinary excited states and generally has a shorter lifetime than the ground state. It can be considered a temporary energy trap or a somewhat … Universalium
