Majorana, the Neutron, and the Neutrino: Some elementary historical remarks

Abstract

At the kind request of the Editor of Hadronic Journal, and of TEC/TNRG (Usa), we recall in this article some elementary historical information about the role played by Ettore Majorana[1-17] with regard to the Neutron, and to the Neutrino. Often we do explicitly insert direct quotations from the original written statements --in particular by Edoardo Amaldi[22-24]--, which in some cases, and for some topics, constitute the main available evidence. We also discuss some recent, unjustified rumors about Ettore Majorana and Enrico Fermi.
