    "abstract": "The general gauge-invariant photoproduction formalism given by Haberzettl is\napplied to kaon photoproduction off the nucleon at the tree level, with form\nfactors describing composite nucleons. Numerical results show that this\ngauge-invariance procedure, when compared to Ohta\u0027s, leads to a much improved\ndescription of experimental data. Predictions for the new Bonn SAPHIR data for\n$p(\\gamma,K^+)\\Lambda$ are given.",
