( Capture of an electron from a low orbital, turning a proton into a neutron.)
Beta decay
seen at quark level.
A quark emits a W+ or W- and changes its flavor (type).Slide2
Beta decay
leading a positron. It travels a short distance before encountering an electron in the material, where it annihilates to two gamma rays (photons) of .511 MeV each.Slide3Slide4Slide5
