The reaction /sup 1/H(..gamma..,K/sup +/)..lambda../sup 0/ is used to compare pseudovector with pseudoscalar coupling for the K..lambda..N vertex. The operator is based on diagrammatic techniques and includes the Born terms along with the K/sup */ and ..sigma.. exchange terms. Obtaining the coupling constants from a least squares fit shows that the data do not prefer one coupling over the other. Implanting the process into the nucleus yields only small differences between the two interactions.
