New Results on Exclusive Production From Nuclei

PDF Version Also Available for Download.

Description

Three new experiments concerning coherent production from nuclei are discussed. Evidence is presented from the Carnegie Mellon-Illinois-Northwestern-Rochester collaboration regarding coherent production of A{sub 2} mesons in collisions of 23 GeV/c {pi}{sup -} with nuclear targets (C, Al, Cu, Ag). The coherent A{sub 2} cross section which vanishes in the forward direction is typically {approx} 2% that of the A{sub 1}. A neutron dissociation experiment conducted at BNL (Rochester-BNL collaboration) has studied the process n {yields} p{pi}{sup -} occurring coherently on nuclei. Using the optical model of Kolbig-Margolis a 30-40 mb cross section was extracted for the scattering of low-mass p{pi}{sup ... continued below

Using the optical model of Kolbig-Margolis a 30-40 mb cross section was extracted for the scattering of low-mass p{pi}{sup -} systems on nucleons for momenta of {approx} 13 GeV/c. A similar experiment conducted at FERMILAB (FNAL, University of Massachusetts, Northwestern, Rochester Collaboration) has indicated that at high energies ({approx} 200 GeV/c) Coulomb excitation of the neutron accounts for the major part of the reaction n + Pb {yields} (p{pi}{sup -}) + Pb. While p{pi}{sup -} production on C is dominated through Pomeranchukon exchange.
