摘要：
Mechanisms of the depolarization of ultracold neutrons in traps reflecting from the trap wall are considered. One is due to neutron spin-flip elastic or quasielastic incoherent scattering from protons of surface hydrogen contaminations. According to the second one, significant depolarization may take place because of a sudden change in the neutron trajectory on reflection from the wall when the neutron moves even at large adiabaticity parameters in nonuniform magnetic field.
