electron capture (plural electron captures)
(physics) A nuclear reaction in which an electron (either free, or from the shell of the atom itself) is absorbed into a nucleus, a proton being converted into a neutron in the process
All of these decay only through alpha decay and spontaneous fission, with the single exception of seaborgium-261 that can also undergo electron capture to dubnium-261. Source: Internet
Among the 15 known isotopes of mendelevium (mass numbers from 245 to 260), the most studied is 256 Md, which mainly decays through the electron capture (α-radiation is ≈10%) with the half-life of 77 minutes. Source: Internet
Beta decay just changes neutron to proton or, in the case of negative beta decay ( electron capture ) proton to neutron so the number of individual quarks don't change. Source: Internet
Because the binding energy of the electron is much less than the mass of the electron, nuclei that can undergo β + decay can always also undergo electron capture, but the reverse is not true. Source: Internet
Electron capture The analogous calculation for electron capture must take into account the binding energy of the electrons. Source: Internet
Isotopes lighter than the stable lutetium-175 decay via electron capture (to produce isotopes of ytterbium ), with some alpha and positron emission ; the heavier isotopes decay primarily via beta decay, producing hafnium isotopes. Source: Internet
