摘要: A method of analyzing inhomogeneous line broadening with crystal-field theory is presented. For actinide ions unfilled f-shells in solids, the most important contribution to f-electron transitions from short-range interactions distorted lattice. Optically active curium are used measure degree radiation damage vicinity their lattice site. The was produced by decay distant 244Cm3+ ions. Fluorescence narrowing (FLN) spectra show that induced α-decay ion 244Cm3+ single crystals LuPO4 and YPO4 has a microscopic nature. Namely, correlation absent between energy levels Cm3+ ions at different local environments. Monte Carlo simulation distortion calculation Cm3+ have been conducted provide quantitative interpretation experimental results. This should be applicable 4f- 3d-ions crystalline materia...
