Abstract: | Topological inelastic cross-sections and average multiplicities for pd and π+d interactions at 195 GeV/c, are obtained from an exposure of the NAL 30″ proportional wire chamber-bubble chamber hybrid system to a positive π+/p beam. We find that 〈nc〉pn = 7.67 ± 0.25, and 〈nc〉π+n = 7.56 ± 0.30, yielding a negative multiplicity difference between pn and pp of 0.50 ± 0.14, and that σn(pp) is approximattely interleaved between σn?1(pn). |
