Abstract
Presented here are the results of the analyses of data obtained from exposures of the 30-inch Fermilab deuterium-filled bubble chamber to mixed, positively charged beam particles incident at 100 GeV/c and proton beam particles incident at 400 GeV/c. The Proportional Hybrid System was used to identify 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. Events with 3 or 4 prongs at 100 GeV/c ere fit to the mass hypothesis $hd \to hpp_{\pi}-$ and a free neutron cross section for $hn \to h (p\pi^-$) is extracted. This cross section is then compared with values obtained at other energies or measured using different techniques. The production of protons with laboratory momenta less than 1.4 GeV/c is also studied for the full event samples at both energies. The inclusive proton cross sections are seen to scale as functions of $M^2$/s and t, leading us to make a detailed study of these cross sections in the context of a Mieller-Regge formalism.
