Blue toruses (in the whole Ne19 image) = 19 protons
Red toruses (in the whole Ne19 image) = 9 nuclear electrons
Atomic number of Ne (10) = protons (19) - nuclear electrons (9)
Neon 19 transform by positron emission of Neon 19 producing Fluorine 19 nucleus (stable)
Ne19 nucleus composed by a central Be7 nanotube surrounded by a six component Deuterium ring. The central Be7 transformed by electron capture of Be7 into Li7, but in case of Ne19 the K electron cannot reach to Be7 part of the nucleus according to D ring shielding (the D ring outer surface have negative charges!)
So the electron comes from photon via pair production, the electron captured and the rest, a positron emitted. No neutrino involved. The energy supplied by nucleus.
