Scattering ofK+Mesons in Emulsion

Abstract

Some new experimental results on the scattering of $K^{+}$ mesons in emulsion are presented, in two energy ranges, $T_K=40\mathrm{} \mathrm{to} 100$ Mev and $T_K=150\mathrm{}\pm 30$ Mev. An optical-model analysis is made of these results, which avoids many of the approximations of previous workers. It is concluded that the $K^{+}$-nucleus interaction is repulsive and that the $K^{+}$-nucleon cross section inside the nucleus is compatible with the observed cross section for free protons.
