⇒ Feynman Diagrams are pictorial representations of the interactions of subatomic particles. ⇒ For example, this shows a Feynman Diagram of beta (β -) decay (see our notes on nuclear equations if you have not done so already): ⇒ Usually, Feynman Diagrams are read from left to right. ⇒ So, here, we can see a neutron decaying into a In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino. In beta plus decay, a proton decays into a neutron, a positron, and a neutrino. β- decay: n ⇒ p + e- +ū e β + decay: p ⇒ n + e + + u e. Let's see the Feynman diagram for a β- decay: [There is also gamma decay but that’s like a by-product of alpha and beta decay: when a nucleus emits an α or β particle (i.e.

Both are described in more detail in the following picture gallery ( Here: Help to understand Feynman diagrams ): Beta minus decay is the transformation of an unstable nucleus accompanied by the emission of an electron and an electron anti-neutrino. Richard Feynman devised a short hand way of writing out particle interactions called Feynman Diagrams.
