The photoproduction process of neutral kaons on a liquid deuterium target is investigated near the threshold region, Eγ=0.8−1.1 GeV. K0 events are reconstructed from positive and negative pions, differential cross sections derived. Experimental momentum spectra compared with those calculated in spectator model using realistic deuteron wave function. Elementary amplitudes as given by recent isobar models simple phenomenological used to study effect new data angular behavior elementary section. favor backward-peaked distribution n(γ,K0)Λ process, which provides additional constraints current kaon photoproduction. present demonstrates that reaction can provide key information mechanism strangeness.6 MoreReceived 3 December 2007DOI:https://doi.org/10.1103/PhysRevC.78.014001©2008 American Physical Society
