Two-dimensional fluorescence spectroscopy of uranium isotopes in femtosecond laser ablation plumes

Two-dimensional fluorescence spectroscopy of uranium isotopes in femtosecond laser ablation plumes

Abstract We demonstrate measurement of uranium isotopes in femtosecond laser ablation plumes using two-dimensional fluorescence spectroscopy (2DFS). The high-resolution, tunable CW-laser spectroscopy technique clearly distinguishes atomic absorption from 235U and 238U in natural and highly enriched...
