The /sup 232/Th(n,f) and /sup 238/U(n,f) cross sections have been measured relative to that of /sup 235/U up to 6 MeV. The best energy resolution was 3 keV at 1.6 MeV. Below the fission threshold of /sup 238/U, intermediate structures are observed. In the /sup 232/Th(n,f) cross section, the broad vibrational resonances located above 1 MeV are resolved into sharp structures which are interpreted as rotational states. The angular anisotropy of fission fragments has been also measured in the same energy range. Thereby, values of K and J have been determined for each structure. The moment of inertia of /sup 233/Th in shape isomeric deformation has been deduced. 4 figures, 1 table (auth)
