Measurement of the yield of doubly charged particles in capture of K/sup -/ mesons by emulsion nuclei
The interaction of K/sup -/ mesons with emulsion nuclei has been studied in order to measure the yield and spectrum of doubly charged particles in sigma/sub K/- stars. Separation of singly and doubly charged particles was carried out by counting the number of delta electrons and measurement of multiple scattering, and also by measuring the width of the track. For ranges greater than 500 ..mu..m the yield of doubly charged particles is close to 2% and their spectrum falls off with energy, extending up to 80--90 MeV. Under these conditions approx.0.023 doubly charged particles are emitted per star. Among particles with range up to 150 ..mu..m the yield of doubly charged particles amounts to about 20% and approx.0.30 doubly charged particles are emitted per star.
