In [Y.V. Radeonychev et al., Phys. Rev. Lett. 124, 163602 (2020)], we reported the observation of the acoustically induced transparency of a stainless steel foil for 14.4-keV resonant gamma-ray photons from a 57Co radioactive Mössbauer source, which is similar to electromagnetically induced transparency and Autler–Townes splitting. In this work, we show that the use of a stainless steel foil with a certain thickness that is enriched in 57Fe and oscillates at the optimal frequency under the same experimental conditions can slow down a single-photon wave packet of gamma radiation with a duration of about 80 ns from the 57Co source to a velocity of less than 6 m/s with a delay of about 100 ns at room temperature.
