摘　　要：The collinear fast ion beam-laser spectroscopy has been used to measure the radiative lifetime of the(23587)°_(9/2) level of the rare earth ions NdII.The measurement was carried out by the interaction between the SOkeV Ndll ion beam and tunable collinear dye laser which resonantly ezcited 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.
