Abstract Scope |
Nuclear magnetic resonance (NMR) spectroscopy was used to study aging in a 7 at.% Ga ä-Pu sample via the 69Ga resonance. The 69Ga NMR was explored under swept-field and fixed-field conditions. The 69Ga data reveals self-irradiation damage manifesting in intrinsic local site disorder seen in field-swept spectra. Subsequent data from spin-relaxation measurements shows a spread of relaxation values across the resonance. Lastly, high-resolution spectra of the narrow component details radiation damage in-growth over ~1 month of storage at 5 K. |
