The New Particles and Their Application in Medicine neutrons, protons, helium ions, negative pions, and heavy ions, have in fact been known and studied by nuclear and high-energy physicists for over forty years. They are new only in the sense that, until recently, the medical community has had little experience with them in the clinic.
