Abstract
The () decay has been measured with stopped positive kaons for a data sample of 216 events. A comparison of the observed spectra with a Monte Carlo simulation determined the form factor. The results are compatible with the data, as estimated from the rule. We also established that the channel can be used to determine the - scattering lengths.
