Abstract

Photoproduction of the K0 from the deuteron and the carbon nucleus has been investigated at the Laboratory of Nuclear Science, Tohoku University in Sendai. The Neutral Kaon Spectrometer and the Neutral Kaon Spectrometer 2 were developed to detect π+ π- pairs coming from the decay of the KS0. The resulting K0 momentum spectra for inclusive K0 photoproduction were compared with theoretical calculations based on isobar models for γ + n → K0 + Λ, utilizing the spectator hypothesis. An upgrade of the inner detectors to enhance the acceptance for the coincidence measurement of the KS0 and Λ is underway. We expect that the exclusive and kinematically complete measurement of the reaction will provide us with direct access to the center-of-mass observables that are important for further understanding the mechanism for strangeness photoproduction.
