21. By changing the number of protons, double electron capture transforms the nuclide into a new element. 22. It is also used in Electron capture detector in gas chromatography for the detection mainly of halogens. 23. Positron emission and electron capture also increase the ratio, while beta decay will decrease the ratio. 24. When the Chandrasekhar limit is reached, that indicates that electron capture has become a feasible process. 25. Other sources may also include beta decay from cobalt-60 and electron capture from copper-60. 26. It decays by positron emission 97 % of the time and electron capture 3 % of the time. 27. At a certain point, they move so fast that instead the pressure drives them to electron capture . 28. These contain strontium-82, which decays by electron capture to produce positron-emitting rubidium-82. 29. Note that in the case of electron capture , bremsstrahlung is emitted even though no charged particle is emitted. 30. In electron capture , an electron " merges " with a proton in the nucleus to form a neutron.
