• The photoneutron cross section of ^<29>Si has been studied by irradiating silicic anhydride, enriched in ^<29>Si, in the X-ray beam of a 15 MeV linear electron accelerator. The photoneutron cross-section shows maxima at about 10.6 and 12.2 MeV. The integrated cross-section form the threshold to 13.0 MeV is 11 MeV・mb. The angular distribution fo photoneutrons has also been measured to fit with a curve of the form α+b sin^2θ. The values for b/a are found to be 2.1±1.0 and 3.9±0.8 for measurements with bremsstrahlung having maximum energies of 11.7 and 12.9 MeV, respectively. The significant features of the photoneutron cross-section and the angular distribution are discussed and compared with theoretical calculations for the E1 transition of a valence neutron.
