We have observed the delayed time spectrum of coherently scattered synchrotron-radiation pulses following a single nuclear Bragg reflection in ⁵⁷Fe-yttrium iron garnet. A new quantum-beat spectrum with more hyperfine information was obtained by our taking B_int perpendicular to the scattering plane (k₀, k_f). The speedup of coherent decay at the Bragg angle due to "enhancement," and the quantumbeat modulation of the coherent decay rate, are shown.
