摘要：

We have investigated photoproduction of K+Λ and K+0 from hydrogen at 4.3 GeV and for u values between -0.2 (GeV/c)2 and -0.7 (GeV/c)2. The data were consistent with a smooth decrease in dσdu towards larger negative u values. The K+ backward photoproduction cross sections appear to be closely similar to the observed cross section for backward π+ photoproduction. The ratio of 0Λ is about 1.7, which rules out pure decuplet exchange in this region of u. The results are consistent with the SU(3) prediction. © 1969 The American Physical Society.
