摘要：
The process of thermal evaporation of rare-earth metals (Ce-Yb) with an incomplete 4f-shell is discussed in terms of electronic structure of their surface. Evaluation of the surface density of neutral intrinsic atoms determining the evaporation process is made. The fact of detachment of Sm atoms in the lowest excited 4f55d6s2-state from the surface is experimentally demonstrated. © Springer Science+Business Media, Inc. 2006.
