摘　　要：本文首次用共振增强消多普勒双光子光谱技术对钐原子四个高激发态偶宇称能级进行了实验研究,得到了这些能级的位置和相应跃迁的同位素位移数据.Experimental investigations have been performed on four high- lying even- parity levels of neutral samarium by resonantly enhanced Doppler-free two-photon spectroscopy for the first time. The energies and isotope shifts of these levels have been obtained.
