A set of experiments has observed the mirror reflection and Bragg diffraction of neutrons at the energy of a low-lying nuclear resonance of 115In. The reflector was a mirror of In metal with the resonance at 1.457 eV. The mirror reflection for different angles of incidence was measured and sets of data showing the relative reflectivities were obtained. For the Bragg diffraction experiment the crystal was a wafer of InP and several examples of Bragg reflections near 1.456 eV were measured.
