Elektroninvetävyys
Elektroninvetävyys refers to the phenomenon of electron capture in nuclear physics. It is a type of beta decay where an atomic nucleus, instead of emitting a positron, absorbs one of its own orbital electrons. This captured electron then combines with a proton within the nucleus, transforming the proton into a neutron and emitting an electron neutrino. The general process can be represented as p + e⁻ → n + νe.
This decay mode is energetically favored when the mass of the parent nuclide is sufficiently greater than
Following electron capture, the vacancy left in the electron shell is quickly filled by an electron from
