An experimental program in strong interaction physics is carried out using counter-spark chamber techniques and a bubble chamber--hybrid system. The experiments have been and are being performed utilizing the accelerators of the National Laboratories at Argonne, Brookhaven and Batavia. The experiments of the electronic detector-spark chamber group include the following: a search for high mass boson resonances and determination of quantum numbers in antiproton-proton systems; a nucleon-nucleon and meson-nucleon elastic and quasi-elastic scattering experiment at the highest energies; a study of inclusive scattering, with associated multiplicity and pseudo-rapidity distributions, for hadrons on protons to hadrons at incident energies up to 175 GeV; an experiment to study the A-dependence of hadronic inclusive scattering at Fermilab; a search for charged, long-lived, massive particles up to the kinematic limit at Fermilab; and a study of hadronic final states produced by 100-GeV pions in association with direct leptons. The bubble chamber--hybrid system group is primarily engaged in several experiments at the Fermilab. A study of ..pi../sup -/p interactions at 147 GeV/c is completed, and a larger investigation of ..pi../sup +/p, K/sup +/p, pp, and ..pi../sup -/p collisions at 147 GeV/c has begun. To the proportional hybrid system has been added a prototype forward gamma detector, enabling the precision measurement of up to 6 photons (3 ..pi../sup 0/'s and/or eta/sup 0/'s). Major aspects of multiparticle production using four different projectiles are being pursued. A precision intercomparison of corresponding processes produced by the different projectiles is underway, using identical experimental conditions. A list of publications is included.
