The measurements of photoneutron spectra for 13 MeV linearly polarized photons on Ta, W, Au, Pb, and Bi targets were carried out at the NewSUBARU facility, Hyogo. The spectra were obtained by adopting the time-of-flight method. The target mass dependence will be discussed based on the experimental data. The detailed results will be presented in the meeting.
