K-CAPTURE在英语中的意思是什么？

电子捕获

Electron capture

电子捕获是质子富集的核素吸收内部原子电子，从而将核质子转变为中子并同时引起电子中微子的发射的过程。 随着原子的能量下降到新的核素的基态，各种光子发射。 电子捕获是同位素的主要衰减模式，其核中质子相对超量，但同位素与其前瞻性子女之间的能量差异不足以使核素通过发射正电子而衰变。 电子捕获是具有足够能量以通过正电子发射衰变的放射性同位素的替代衰变模式。 它有时被称为反β衰变，尽管该术语也可以指电子抗中子与质子的相互作用。 如果母原子和子母原子之间的能量差小于1.022MeV，则不能使用正电子发射，因为没有足够的衰减能量来允许它，因此电子俘获是唯一的衰减模式。 例如，铷-83只能通过电子捕获而衰变到氪83。

Electron capture is a process in which a proton-rich nuclide absorbs an inner atomic electron, thereby changing a nuclear proton to a neutron and simultaneously causing the emission of an electron neutrino. Various photon emissions follow, as the energy of the atom falls to the ground state of the new nuclide. Electron capture is the primary decay mode for isotopes with a relative superabundance of protons in the nucleus, but with insufficient energy difference between the isotope and its prospective daughter for the nuclide to decay by emitting a positron. Electron capture is an alternate decay mode for radioactive isotopes with sufficient energy to decay by positron emission. It is sometimes called inverse beta decay, though this term can also refer to the interaction of an electron antineutrino with a proton. If the energy difference between the parent atom and the daughter atom is less than 1.022 MeV, positron emission is forbidden as not enough decay energy is available to allow it, and thus electron capture is the sole decay mode. For example, rubidium-83 will decay to krypton-83 solely by electron capture.
