Description

Quasi-free K+ photo-production in the 12C(γ,K+) reaction has been investigated in a photon energy range of 0.7-1.1GeV. Differential cross sections for the quasi-free process of the 12C(γ,K+) reaction have been obtained and they are compared with a calculation of a quasi-free K+ photo-production. The effective proton number Zeff=4.2±0.6 obtained from the experiment was in good agreement with a calculation of a semi-classical attenuation model. ((orig.))
