Outline of Final Research Achievements

Neutron resonance absorption spectroscopy (N-RAS) with a pulsed neutron source can distinguish the dynamics of individual nuclides by their resonance peak widths That can identify the motions of a particular nuclide with its resonance energies, and analyze the dynamics of nuclides from the Doppler broadening of the resonance peaks due to their thermal motion. We applied this technique to the nondestructive thermometry of the object inside.
In this study, we applied prompt gamma-ray type N-RAS, but it is inefficient for imaging because it needs spatial beam scan. If we put multiple nuclides each location, it can measure the temperature of the desired location at the same time. We measured the resonance absorption spectrum of a heated sample which was composed with multiple nuclides. The analyzed nuclides were Ta-181, Ag-109 and Sm-147 in the same sample object. Each nuclide indicates a good consistency. The difference between analyzed and sample temperature is under 5 K in each nuclide.
