Abstract The collinear fast ion beam-laser spectroscopy has been used to measure the radiative lifetime of the (23537)°9/2 level of the rare earth ions NdII. The measurement was carried out by the interaction between the 30keV NdII ion beam and tunable collinear dye laser which resonantly excited a metastable level to the (23537)°9/2 level, and by the observation of its time-resolved decay downstream. The lifetime value obtained from a fit program was 27.6±0.9ns . The result may provide a possibility of determining the unknown configuration of the (23537)°9/2 level.
