Abstract

The elastic and topological $\bar{p} p$ cross sections have been measured at 48.9 GeV/c in the Fermilab proportional-wire-chamber-30-in.-bubble-chamber hybrid spectrometer. The elastic cross section is 7.81±0.24 mb and the slope of the elastic differential cross section at $t = 0$ is 13.4±0.8 ${GeV}^{- 2}$ . Further, the moments of the inelastic topological-cross-section distribution are $〈 n_{c} 〉 = 5.69 \pm 0.03$ , $\frac{〈 n_{c} 〉}{D} = 2.10 \pm 0.02$ , and $f_{2}^{cc} = 1.67 \pm 0.12$ .
