Nuclear Bragg scattering of synchrotron radiation from isotopically enriched /sup 57/Fe/sub 2/O/sub 3/ has been observed at a signal-to-noise ratio of 100:1 without delayed-coincidence techniques. The use of a high-resolution premonochromator providing a 5-meV energy spread and 0.4'' collimation allows for high-resolution studies of dynamical diffraction effects. In particular, the observed intensity of the pure nuclear (7,7,7) reflection implies a dramatic decrease of the effective lifetime due to coherent scattering.
