Collinear fast-beam laser-spectroscopy has been used to measure the hyperfine structure and isotope shift of several indium and tin isotopes. The related experimental techniques are described, including the preparation of mass-separated beams of neutron-deficient indium and tin isotopes at the GSI on...

摘要: The paper collects some general properties of the description of an unstable particle considered byHorwitz andMarchand. It is proved generally, that the initial decay rate of finite energy states equals to zero.收藏 引用 批量引用 报错 分享 ...
Tritium is unstable and radioactively decays at a half-life of 12.32 years. Tritium decays into helium-3.Isotopes of Hydrogen The periodic table of elements outlines all the simplest chemical substances and the information regarding their atoms. Elements are the simplest chemical substances in that ...
This decay releases radiation (alpha, beta, or gamma rays) as the unstable isotopes break down into more stable forms. Radioactive minerals are used in dating geological formations, as the rate of decay (half-life) is consistent for specific isotopes. Examples: Uraninite (UO₂): A highly...
Isotopes of Elements- Isotopes refer to elements with nuclei having the same number of protons, but differing numbers of neutrons, so that the masses of contrasting isotopes differ by one to a few neutrons. To learn more about the Types, Examples, Physic
programs were used to find suitable reactions for the production of unstable 186Au in different neutron channels that would allow the measurement of the energies and decay properties of low-lying levels in 186Pt, populated in the 尾-... EE Jiang,C Deng - American Physical Society 被引量: 0...
A mixture of stable and unstable isotopes of krypton is produced by slow neutron fission of uranium in nuclear reactors as Kripron-85, its most stable isotope. It is used to detect leaks in sealed containers, to excite phosphors in light sources with no external source of energy, and in me...
Isotopes:Natural yttrium is composed of yttrium-89 only. 19 unstable isotopes are also known. Properties:Yttrium has a metallic silver luster. It is relatively stable in the air except when finely divided. Yttrium turnings will ignite in air if their temperature exceeds 400°C. ...
Nuclear isotopes that have a "magic number" of protons or of neutrons are more likely to be stable, or if unstable, have a longer decay half-life, than nuclei with non-magic numbers of protons and neutrons. The explanation for this (involving the Pauli exclusion principle) is similar to ...
