nuclear transition
51Vibronic transition — A vibronic transition denotes the simultaneous change of vibrational and electronic quantum number in a molecule. According to the separability of electronic and nuclear motion in the Born Oppenheimer approximation, the vibrational transition and …
52Planta de energía nuclear de Savannah River — El Savannah River Site tal como se ve desde el espacio. El Savannah River Site es un centro de procesamiento de materiales nucleares en el estado de Carolina del Sur, situado en terrenos adyacentes al río Savannah cerca de Augusta, Georgia. Es… …
53B movies (Transition in the 1950s) — The 1950s mark a significant change in the definition of the B movie. The transformation of the film industry due to court rulings that brought an end to many long standing distribution practices as well as the challenge of television led to… …
54Magnetic dipole transition — The interaction of an electromagnetic wave with an electron bound in an atom or molecule can be described by time dependent perturbation theory. Magnetic dipole transitions describe the dominant effect of the coupling to the magnetic part of the… …
55TNP1 — Transition protein 1 (during histone to protamine replacement), also known as TNP1, is a human gene.cite web | title = Entrez Gene: TNP1 transition protein 1 (during histone to protamine replacement)| url =… …
56Mössbauer 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 …
57Mössbauer 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… …
58Photon — This article is about the elementary particle of light. For other uses, see Photon (disambiguation). Photon Photons emitted in a coherent beam from a laser Composition Elementary particle …
59Internal conversion — This article is about the nuclear process. For the chemical process, see Internal conversion (chemistry). Internal conversion is a radioactive decay process where an excited nucleus interacts with an electron in one of the lower atomic orbitals,… …
60Mössbauer 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… …
