Angular distribution of L x rays of Au and Pb following photoionization by synchrotron radiation has been measured at the incident photon energies corresponding to the energy between ${L}_{3}$ and ${L}_{2},$ between ${L}_{2}$ and ${L}_{1},$ and above ${L}_{1}$ absorption edges. No evidence of L x-ray anisotropy was observed within the experimental errors for all incident photon energies, but in the case of ${L}_{l}$ x rays an anisotropy of a few percent might be possible. The experimental results are in good agreement with the theoretical prediction.
