【Abstract】 The setup of the collinear fast ion-beam-laser spectroscopy (CFIBLS) with the Fabry-Prot interferometer is described and the method of analyzing the experimental data is given. The hyperfine structures of the transitions from metastable 4f 95d 7H 0 8 to excited states 4f 96p 3/2 (15/2, 3/2) for 159 TbII was measured by CFIBLS. For the high spectral (sub-Doppler) resolution of CFIBLS, the HFS constants A and B of the involved levels were obtained with small errors.更多还原
