Blue toruses = 139 protons
Red toruses = 82 nuclear electrons
Atomic number of La139 = protons (139) - nuclear electrons (82) = 57, with structure of 1T+8D + 6T + 12 He4 + 18T. Other possible structure is 1T+20D + 6T + 12D + 18T.
Central rod of La139 is 1T+8D as P31 stable nuclei.
The six member ring consists by 6 Tritium nuclei.
the next 12 member ring consists of 12 Helium4 nuclei.
The outer ring builds up by 18 Tritium nuclei.
