【 摘 要 】

Theoretical models for kaon photoproduction with spin 5/2 nucleon resonances have been plagued with the problem of interaction consistency. A number of studies predicted that a model with a consistent interaction leads to a better agreement with data. In this study a model with consistent interaction (model 2) is compared to the old model, which utilizes an inconsistent interaction (model 1), as well as to experimental data. The unknown parameters in scattering amplitude are extracted from fitting to 7400 experimental data points. This is performed by minimizing the X2/N value. It is found that model with a consistent interaction (model 2) is more suitable for explaining experimental data.
