We have investigated for the first time the coherent productions of the A/sub 2/ + and K/sup */ + (1430) mesons in the nuclear Coulomb field of Pb and Cu. The experiment was performed at Fermilab using a high resolution forward spectrometer consisting of proportional and drift chambers plus a liquid argon photon calorimeter. The incident momentum was 200 GeV/c. We found that at this momentum strong production mechanisms give very small contributions. The data were analyzed allowing for a small amount of hadronic background to interfere with the dominant electromagnetic production of the A/sub 2/ + K/sup */+ (1430) mesons. The results were used to extract values for the radiative decay widths of these mesons. The accuracy of these values is limited by the low statistics we had.
