摘要：
We measured differential cross sections and photon beam asymmetries for the (gamma) over right arrowp -> K+Lambda and (gamma) over right arrowp -> K+Sigma(0) reactions at forward angles by using linearly polarized photons ranged from 1.5 GeV to 2.4 GeV at the SPring-8/LEPS facility. The photon beam asymmetries for both the reactions have been found to be positive and increase with the photon energy. The resonance-like structure found in the CLAS and SAPHIR data was seen in differential cross sections for the K+Lambda reaction, The differential cross sections indicate the forward peaking for the K+Lambda reaction, but not for the K+Sigma(0) reaction.
