Abstract
Intermediate structure has been observed in the photofission cross section of measured with a photon energy resolution <500 eV. The gamma rays, variable in energy, were obtained from the (, ) reaction on several nuclei. The average spacing of the observed photofission resonances at an excitation energy of 6.16 MeV is 1.6±0.4 keV. The average areas of the resonances are compared with theoretical expectations for a double-humped and a triple-humped barrier.
