 In this work we studied lanthanides by using a full-relativistic description of the electronic structure of allshells. We tested the so obtained wave functions in binding energies in stopping power calculations, considering separately the contributions of the valence and bound electrons. Present results for protons in Gd and Er state doubts on the present knowledge of the stopping values in lanthanides, and shows that an appropiate characterization of the 4f-electrons plays a decisive rol.
