Abstract

We have observed the coherent production of K^∗+ (890) on nuclei ranging from C to Pb at 10, 13 and 16 GeV/c. Fitting a model of coherent production, including strong and electromagnetic interactions and their interference, to the measured coherent production cross section we find the strong contribution to the dominant and determine the upper limit of the radiative decay width $Γ(K^{∗+} → K^{+} γ) < 80 keV$ with 95% confidence.
