Abstract

Combined data on the reactions pp → ppπ^o, pp → pnπ⁺and pn → ppπ^- at 7.0 GeV/c is used to study the peripheral reaction N₁N₂ → N₃(N₄π) in terms of the isospin amplitudes M_I^Ix (where I_x and I are the isospins of the exchange particle and the (N₄π) combination respectively). The total and differential cross sections and the mass distributions M(N₄π) of these isospin states are discussed in terms of different possible solutions. Similar analysis at 28.5 GeV/c shows that the M_{1 2}⁰ cross section decreases slowly with incident momentum in agreement with pomeron exchange.
