0.1 < - t < 15 GeV2 or until the cross-section dcr/dt drops below 10-33 cm2/GeV2/c2. 2. Using proton recoil measurements above, the mesonic missing mass crosssections over a wide range of possible mass and momentum transfer. 3. The multiplicity and momentum distribution of the charged and neutral particles in the mesonic shower over a wide range of mass and momentum transfer. We should be able to identify completely a large class of such events. 4. Reactions of the type w + p + (2n+l) w + p have a particular interest, inasmuch as such combinations of an odd number of pions might represent Regge recurrences of the pion which could be produced by a coherent diffraction process with substantial cross-section at 100 GeV. l 1M P.
