Quasi-two-body reactions at 50-200 GeV

We propose a wire spark chamber experiment to study peripheral reactions which lead to a final state containing one or more resonances. An example is {pi}{sup +} {yields} {rho}{sup o}{Delta}{sup ++}. The experiment is intended to measure a variety of such processes simultaneously, for pions, kaons, and protons incident on protons. The range of four-momentum transfers will be from essentially zero to about 1 (GeV/c){sup 2}. The major goals of the experiment may be summarized as follows: 1. To study the s and t dependence of the cross sections for peripheral processes in order to check various dynamical models. 2. To search for new meson and baryon resonances and in favorable cases to determine their quantum numbers. 3. To study {pi}-{pi} and K-{pi} scattering in those reactions which produce baryon resonances predominantly by pion exchange
