Abstract

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 8.3–12.4MeV 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.
