We have measured (K-,K+) reaction at 1.67 GeV/c K- at the KEK proton synchrotron. A scintillating fiber active target was employed to view both secondary interactions and decays of particles produced in the (K-,K+) reaction. This tracking capability for the vertex region provides us for studying the fate of Ξ- hypernuclei, which is advantageous over the previous two experiments. We present a preliminary result on the production cross sections for Ξ12 Be, and also on the branching fractions into the decay modes with charged particles and/or Λ hyperon(s).
