Text: "Relativistic self trapping of hadrons." Matter-antimatter interactions. Points out that an electron and a space-like positron in the ortho state combine to form what appears to be a photon. A spacelike state is the classical counterpart of a virtual state in quantum electrodynamics. Lettere al Nuovo Cimento della Societa italiana di fisica. Series 2, 20(17), Dec. 24, 1977. p. 645-648.
