| Outline of Final Research Achievements |
A slow-positron beam apparatus, which uses spin-polarized positrons emitted from a radioisotope, has been developed. By using a solid rare gas moderator for obtaining mono-energetic slow-positrons, it generates a spin-polarized slow-positron beam with a diameter of 0.2 mm (FWHM) at a position for transmission-type remoderator.
A low-energy positron diffraction (LEPD) pattern from a Ge(001)-2x1 structure has been observed with an accelerator-based non-polarized slow-positron beam, whose brightness was enhanced by a transmission-type remoderator and optics we had developed.
