| Research Abstract |
In quest for the realization of holographic neutron-optical elements for neutron interferometers and focused small angle scattering apparatus at cold and very cold neutron wavelengths, we have clarified the neutron diffraction properties of volume plane-wave holograms recorded in photopolymerizable nanoparticle-polymer composites under holographic exposure at a green (532 nm) wavelength. We have also demonstrated the mirror operation with the 90 % diffraction efficiency at a very cold neutron wavelength of 4.1 nm by use of a free-standing nanoparticle-polymer composite film as well as the three-port-beam-splitter operation at a cold neutron wavelength of 1.7 nm with the 1:1:1 division ratio. As a result, we have shown the feasibility of photopolymerizable nanoparticle-polymer composites as holographic neutron-optical elements.
