Interactions Of 115 Bev C Kminus Mesons In Emulsion PDF Download

The results of an analysis of 1240 interactions in Ilford K-5 emulsion are presented. A detailed study of the characteristics of several hundred stars was made. The emission of hyperons, K mesons, pi mesons and hypernuclei was determined. Each star was studied under 2500X magnification for the existence of a double center, a recoil and Auger electrons. A search was made for free lambda hyperons emitted from these interactions, and five events were located. The analysis is directed toward determining how often the strangeness of the K(minus) meson is accounted for by the emisssion of a visible strange particle or a neutral hyperon. The probability of a lambda hyperon being trapped to form a hypernucleus can then be estimated. The observed characteristics of parent stars was correlated with recent developments in the proposed model for heavy hyperfragments production. The study is divided into three projects: an analysis of charged hyperon production; an examination of interactions in flight; and a determination of the frequency of lambda hyperon production, both free and bound.
