In '''{{w|gamma decay}}''', an unstable nucleus (represented by the lumpy, prolate nucleus in the diagram – representing a high-energy {{w|nuclear isomer}}) emits a high-energy photon known as a {{w|gamma ray}} and settles into a stabler, lower-energy state. | In '''{{w|gamma decay}}''', an unstable nucleus (represented by the lumpy, prolate nucleus in the diagram – representing a high-energy {{w|nuclear isomer}}) emits a high-energy photon known as a {{w|gamma ray}} and settles into a stabler, lower-energy state. | ||
− | In '''{{w|electron capture}}''', a proton-rich atom | + | In '''{{w|electron capture}}''', a proton-rich atom slurps an electron from the K or L electron shell. This converts a proton into a neutron and emits an electron neutrino. No 'slurp' sound is actually present in a real electron capture event. {{Citation needed}} |
In '''{{w|positron emission}}''', or beta plus decay, a proton-rich nucleus emits a W⁺ boson, converting one proton into a neutron. The boson, in turn, decays into a positron (the beta plus particle) and an electron neutrino. Again, the main diagram shows only the beta particle, presumably for simplicity, the nucleon conversion being shown separately. This is much rarer than beta minus decay. | In '''{{w|positron emission}}''', or beta plus decay, a proton-rich nucleus emits a W⁺ boson, converting one proton into a neutron.
