Presented here are the results of the analyses of data obtained from exposures of the 30-inch Fermil.ab deuterium-filled I.ubble chanber to mixed, positively charged beam particles incident at ~00 GeV/c and proton beam particles incident at 400 GeV/c. . . The Proportional Hybrid System was used to identif~ the beam particles, and on low multiplicity events, to improve fast track momenta for the 100 Ce.V/c data sample. Topological hd and hn cross sections are extracted from both data samples.

... nts with 3 or 4 prongs at 100 GeV I c .:.re fit to the mass hypothesis hcl+hpPlf -and a free neutron cross section for hn+h(p~-) is extracted. This · cross section is then compared with values obtained at other energies or measured using different techniques. The production of protons with lcborat:ory momenta less than i"~4 C£V/c is also stu-·died for the full event samples at both energies. The inclusive proton cross sections are seen to scale as functi~ns of }f /sand t, leading us to make a detailed study of these cross sections in the context of a Mieller-Regge formalism. i i i To my father Jb raham Harris Brody City College of New York B.
