The total attenuation cross sections of rare-earth elements have been measured in a narrow beam good geometry using a high-resolution hyper pure germanium detector in the energy range 6–85keV. The data have been used to derive the K-shell photoeffect cross sections at the K-edge τK, the oscillator strength gK and the K-jump ratio JK of the elements La, Ce, Pr, Nd, Sm, Gd, Dy, Ho and Er. The τK and the gK values have been calculated by a method, which eliminates the requirement of subtracting the theoretical scattering contribution. The best-fit coefficients for the cross sections, jump ratios and oscillator strengths facilitate E- and Z-wise interpolation in the energy range 6–85keV and Z range 57–68.
