Abstract
It is shown that quasielastic scattering of ultracold neutrons due to diffu sive motion of scatterers at the surface of liquid polymer (fomblin) or ads orbed hydrogenous contaminations of the surface of neutron traps may be pos sible reason of their energy spreading during long storage time in closed t raps, which was observed in the recent experiments.
