| Outline of Final Research Achievements |
The final target of this study at the start was, hitherto unreported, the generation of neutron beams carrying orbital angular momentum (OAM) by controlling the phase of wavefunctions. Towards this goal, in this study we proposed some neutron optical elements such as forked diffraction gratings and polygonal slits. A prototype micrometer-sized forked diffraction grating has been designed with wave simulations and implemented using proton microbeams. The present results represent a first step toward neutron beams with OAM.
