dc.description.abstractFor ultracold neutrons with a kinetic energy below 10 neV, strong scattering, characterized by 2πl꜀ / λ ≤ 1, can be obtained in metamaterials of C and ⁷ Li. Here l꜀ and λ are the coherent scattering mean free path and the neutron wavelength, respectively. UCN interferometry and high-resolution spectroscopy (nano-electronvolt to pico-electronvolt resolution) in parallel waveguide arrays of neutronic metamaterials are given as examples of new experimental possibilities.
