Radioactive decay in which an orbital electron is captured by the nucleus of the radionuclide.
a radioactive decay process in which an electron is spontaneously incorporated into a nucleus; the atomic number of the atom decreases by 1.
the decay of an unstable nucleus by capturing, or picking up, an electron from an inner orbital of an atom
3/4 Radioactive transformation in which the nucleus absorbs an electron from an inner orbital. The remaining orbital electrons rearrange to fill the empty electron shell and in so doing energy is released as electromagnetic radiation at X-ray wavelengths and/or as electrons (such electrons are called Auger electrons).
A reaction in which the nucleus of an atom captures a 1s electron.
A radioactive decay process in which an orbital electron is captured by and merges with the nucleus. The mass number is unchanged, but the atomic number is decreased by one.
a mode of radioactive decay involving the capture of an orbital electron by its nucleus. Capture from the particular electron shell is designated as "K-electron capture," "L-electron capture," etc. X-rays are produced.
A mode of radioactive decay involving the capture of an orbital electron by its nucleus resulting in conversion of a proton to a neutron.
Electron capture (sometimes called Inverse Beta Decay) is a decay mode for isotopes that will occur when there are too many protons in the nucleus of an atom and insufficient energy to emit a positron; however, it continues to be a viable decay mode for radioactive isotopes that can decay by positron emission. If the energy difference between the parent atom and the daughter atom is less than 1.022 Me V, positron emission is forbidden and electron capture is the sole decay mode. For example, Rubidium-83 will decay to Krypton-83 solely by electron capture (the energy difference is about 0.9 MeV).
