摘　　要：在介绍晶体场导致稀土离子“能级分裂”和4fN组态内单光子跃迁的宇称禁戒的“部分解除”的基础上,讨论了该组态内单光子、双光子跃迁及电子拉曼散射几率计算的国际动态,总结了我们在此领域的工作并提出了进一步工作设想。Firstly, the crystal-field model is reviewed with emphasis on the energy-splitting and the lift of parity-forbidden rule for d-d or f-f one-photon ED transition caused by it. Then based on our work the progress of transition intensity calculations for one-photon, two-photon transitions and electronic Raman scattering within the 4f^N configuration of rare earth ions are commented on and some suggestions on further directions in this field are proposed.
