what interaction is responsible for electron capture
The weak interaction is responsible for beta decay. The exchange particles for the weak interaction are the W+ , the W-and the Z0. Consider Î² decay. n â p. We can describe the process as follows. A neutron changes into a proton by emitting a W - , which quickly decays into an electron and an antineutrino.ote: that in some reactions quarks can be created in quark-antiquark pairs, but the net flavour of quarks before and after is unchanged as they created pairs cancel. Another example of the weak interaction is the interaction between a proton and an electron called electron capture.
1 Electron CaptureIt is possible for a proton in the nucleus to âcaptureâ an electron and turn into a neutron releasing a neutrino e p e n e. 2  9. 3  Feynmanâs Diagram for e-captureThe force responsible for electron capture is the weak force.4  So, the exchange particle is the W+. 10. 2  Electron â Proton CollisionWhen an electron and a proton collide the proton turns into a neutron releasing a neutrino e p e n e. 3  11. 4  Feynmanâs Diagram for e- - p collisionsThe force responsible for this collision is the weak force.
