A study of the ultra-cold neutron up-scattering at reflection from solid surface
Published online by Cambridge University Press: 31 January 2009
Abstract
We describe a method and present the results of the measurements ofspectral change of stored ultra-cold neutrons and the sub-barrier neutronup-scattering from solid surfaces to the energy range higher than theboundary energy of the sample. The method consists in measuring the neutron absorption curvesas a function of UCN storage time and the thickness of the absorbers. The quasi-elastic and inelastic UCN up-scattering probability is determinedat room temperature. The neutron spectra are inferred in monochromatic and more detailedapproximations.
