Abstract

The differential cross section for $π^{+} p$ elastic scattering has been measured at $13.8 \frac{GeV}{c}$ for $0.7 < | t | < 3.8 {(\frac{GeV}{c})}^{2}$ . The cross section is found to be equal to that previously obtained for $π^{-} p$ elastic scattering, except in the region $| t | = 2.8 {(\frac{GeV}{c})}^{2}$ , where the $π^{+} p$ data do not show the prominent dip observed in $π^{-} p$ scattering. Data have also been obtained for $13.8 - \frac{GeV}{c} K^{+} p$ elastic scattering for $0.8 < | t | < 2.2 {(\frac{GeV}{c})}^{2}$ .
