L X-ray line production cross sections for Eu, Tb and Er elements have been measured as a result of <sup>7</sup><sub>3</sub>Li ion bombardment at energies from 4.2 to 19.6 MeV. The corresponding L<sub>1</sub>-, L<sub>2</sub>- and L<sub>3</sub>-subshell ionization cross sections have been calculated and have been compared to the predictions of the ECPSSR and SCA theories. Possible reasons for observed disagreements between experiment and theory are discussed.
