The flux of neutrons with energies in the range 0.2 x 10/sup -3/--25 x 10/sup -3/ eV, equal to the number of ultracold neutrons (UCN) escaping per unit time from a vessel storing them, is registered by an external detection system surrounding the vessel. For the maximum UCN confinement time attained (approx.23 sec), corresponding to 1.4 x 10/sup 3/ collisions of a UCN with the vessel walls, between 75% and 100% of all the UCN accumulated in the vessel escape from it by inelastic scattering at the walls.
