Description

Ultra-cold neutrons (UCN) are produced in superfluid helium by single- and multi-phonon excitation. The UCN production rate density RII via multiphonons can be larger than that by one-phonon excitation RI being due to the dependence of the incident neutron spectral flux density dφ/dλ on the wavelength λ.
