Abstract
The K0 photoproduction process is investigated in the threshold region, Eγ = 0.8-1.1 GeV at LNS-Tohoku. K0 events are measured via π+π- decay channel. Obtained momentum spectra for the deuteron target are compared with those calculated in the spectator model using a realistic deuteron wave function. Recent isobar models and a simple phenomenological model are used as elementary amplitudes to investigate the effect of the new data on the angular behavior of the elementary cross section. The data favor a backward-peaked angular distribution of the elementary n(γ, K0)Λ process in the center-of-mass (c.m.) system, which provides additional constraints on current models of kaon photoproduction. The present study shows that the n(γ, K 0)Λ reaction can provide key information on the mechanism of the photoproduction of strangeness.
