Physics, Astronomy & Cosmology / Re: What's the point of a Neutron?
« on: 28/04/2015 18:01:26 »I have the very naïve view that the neutron is a proton that somehow has an electron forced into it that only survives when it has proton companions otherwise ejects the electron after 15 minutes or so.
Then look at Beta Decay Plus, in which proton turns to neutron, by emission of positron and neutrino..

If neutron is proton+electron, then how can proton change to neutron, in proton-rich isotopes.. ? Basically reverse situation.
Going your above path of thought, proton would be neutron with positron..
But that's not the case.
PS if it all began as a soup of quarks where did the electrons come from that are apparently not built from quarks but a different type of particle ?
Electrons can be created in pair production from photons with energy exceeding 1.022 MeV.
