Abstract

$K^{+}$ interactions in nuclear photographic emulsion have been studied at three effective mean $K^{+}$ energies: 54 Mev, 95 Mev, and 140 Mev. The cross section for inelastic interaction is found to increase slightly with energy. The scattering appears to be $s$ -wave, $T = 1$ , at low energies, with $p$ -wave scattering becoming appreciable above about 100 Mev.
