The Feynman diagram for this process is below. The neutron ejects a W – boson, which then immediately decays to an electron and antineutrino. The neutron becomes a proton. Draw a Feynman diagram that shows a proton undergoing positive beta decay. Show answer. Answer: The proton decays into a neutron while emitting a positron and an electron neutrino. The decay is mediated by the W boson (W+) You are done with the topic: Atomic, Nuclear, Particle Physics.

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. when we have alpha or beta decay), the nucleus will usually be left in an excited state, and so it can then move to a lower energy state by emitting a gamma ray photon (gamma radiation is very hard (i.e. very high-energy) radiation) – in the same way that an atomic electron can jump to a lower … 2009-04-28 You get these gems as you gain rep from other members for making good contributions and giving helpful advice. If you Google 'feynman diagram beta decay' you'll see that, for the beta minus decay, on some the anti-electron neutrino's arrow is pointed away from the W-, and in others it's pointed towards.

This process assumes a simple form; namely, The Feynman diagram of the process, written in terms of the particles we know today and of massive Majorana neutrinos, is given Figure 1. Draw the Feynman diagram for the following: Pair production of an electron and a positron from a photon. Annihilation of an electron and a positron into two photons.

submission. Apr 11, Hi all After many months of contemplating, coming up with tattoo ideas, waiting a few months to see if I still like that idea, etc etc, I've settled on.
