A phenomenon is predicted in which a high-energy particle beam undergoing diffraction scattering from a nucleus will acquire components corresponding to various products of the virtual dissociations of the incident particle, as p -> A+K + or ir~ -> p-\-n. These diffraction-produced systems would have a characteristic extremely narrow distribution in transverse momentum, and would have all the same quantum numbers as the initial particle; i.e., the same spin, isotopic spin, and parity. The process is related to that discussed in the preceding paper, and has the same effective energy threshold.

observed with a mass of 1385 Mev. Two types of resonances have been predicted that might relate this observation to other elementary-particle interactionll: (1) P 3/2 resonances in the A:rr and Z." systems predicted. 7 8 FOOTNOTES UCRlo-9675
