Abstract

Three (${K}^{\ensuremath{-}}, p$) scattering events have been found in following 560 cm of negative $K$-particle track in nuclear track emulsion. The masses of the negative $K$-particles as calculated from the ranges and angles of the secondaries are not inconsistent with the mass of the ${\ensuremath{\tau}}^{+}$ particle. 1634 cm of track length from other experiments in which no (${K}^{\ensuremath{-}}, p$) scatterings were observed have been added to the 560 cm of this experiment to give an elastic scattering cross section of 44 millibarns.
