Measurements of the 152Sm([gamma],n) Cross Section with Laser-Compton Scattering [gamma] Rays and the Photon Difference Method

The cross sections of the 152Sm(γ,n) and 197Au(γ,n) reactions have been measured with the laser-Compton scattering (LCS) γ beam in the 8.3-12.4 MeV energy range. The photon difference method has been used for LCS γ rays in the data analysis for the first time. The present data for 197Au measured as the standard are in agreement with the preceding data and the recent recommendation. On the other hand, the preceding data for 152Sm at 8.3 MeV are twice as large as the present data.
