High-precision photon-induced ²³²Th(γ^→,f) experiments give access to information about the fission process from measuring the kinetic energy, the mass and the angular distribution of the fission fragments using a Frisch-Grid Ionization Chamber. This contribution will show data from an experimental campaign conducted at the High Intensity Gamma-ray Source facility using quasi-monochromatic photon beams between 6.2 MeV and 13 MeV. A comparison of the measured mass distributions to previous experiments using bremsstrahlung will be presented.
