Description

In connection with the problem of anomalous losses of ultracold neutrons (UCN) in the storage in the material traps the measurements of quasi-elastic scattering of UCN in collisions with trap surface coated with beryllium have been carried out. It was observed that the probability of quasi-elastic scattering of UCN from energy interval 0-77 neV to 90-200 neV is (2.2+/-0.2)x10-8 per collision therefore the process of quasi-elastic scattering cannot explain the effect of anomalous losses which is on the level 3x10-5
