Abstract :
A qualitative model describing the surface of rare earth metals with an uncompleted 4f electron shell (Ce-Yb) and the process of thermal evaporation from this surface is proposed. The model is based on a correlation established between the energies of the lowest-lying levels of the 4fN-15d6s2 configuration and the temperatures of equal saturated-vapor pressures of these metals. The possibility of experimental confirmation of the model is suggested.
