【摘要】 <正>Natural radiative lifetimes of 53 odd-parity highly excited levels of singly ionized samarium in the energy range from 26599.08 to 36107.66 cm^-1 have been measured by time-resolved laser-induced fluorescence（LIF） technique in an ionic plume produced by laser ablation.The fundamental frequency and second harmonic of a dye laser have更多还原
