| Abstract: | Firstly,the crystal-field model is reviewedwith 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 progressof 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. |

| Keywords: | optical transition intensity rare-earth ions crystal field many-body perturbation theory |
