摘要：

The first measurement of C-12(gamma,K+) has been performed in a photon energy range of 0.8 less than or equal to E(gamma) less than or equal to 1.1 GeV. The differential cross sections are compared with a calculation which assumes a quasifree Lambda-producing C-12(gamma,K+) process. The deviation of experimental values from the calculation is explained in terms of bound Lambda residual states. The differential cross section ratio of C-12(gamma,K+) to p(gamma,K+)Lambda is 4.2+/-0.6, which is in good agreement with a calculation using a semiclassical model.
