We performed an experiment to reconstruct a three-dimensional NRF–CT image, with isotope selectivity, of enriched lead isotope rods (208Pb) together with a set of different rods, including another enriched isotope (206Pb), iron, and aluminum rods, inserted into an alu-minum cylindrical holder. Using a laser Compton scattering (LCS) gamma-ray beam at UVSOR-III we excited the J????=1- NRF level at 5.512 MeV in 208Pb., 日本原子力学会 2021年春の年会}, title = {Three-Dimensional Nondestructive Isotope-Selective Tomo-graphic Imaging of 208Pb distribution via Nuclear Resonance Fluorescence}, year = {2021} }
