Feynman Diagrams (Part 2)

In Diagram E  : This represents electron capture. A proton captures an electron and becomes a neutron and an electron neutrino.

In Diagram F : This represents a neutrino-neutron collision. A neutron absorbs a neutrino and forms a proton and an electron.

In Diagram G : This represents an antineutrino-proton collision. A proton absorbs an antineutrino and emits a neutron and an electron.

In Diagram H : This represents an electron-proton collision. They collide and emit a neutron and an electron neutrino
