The energy dependence of the reflection of ultracold neutrons from the surface of strongly absorbing Cdm and Gd155 elements is measured. The "metallic" reflection of neutrons was observed in Gd155 for which the real part of the potential for interaction with neutrons is much smaller than the imaginary part.
