Outline of Final Research Achievements

The beta-detected nuclear magnetic resonance (beta-NMR) technique, using implantation of short-lived beta-ray emitting nuclei into materials, exhibits extremely high sensitivity to the NMR detection and allows us to study the microscopic behavior of dilute impurity atoms in materials. In the present study, we have newly established the production of spin polarized nuclear beams of short-lived Li, N, P and Cu isotopes via nuclear reactions and have applied them as beta-NMR probes to the materials science studies.
