The absolute electrofission cross sections of Au and Ta were measured in the energy interval 40-250 MeV. Pronounced inflexions of the (e,f) curves are observed for both Au and Ta around 200-220 MeV, which are signatures of structures in the corresponding photofission cross-section curves. We show that these ( gamma ,f) structures are related to peculiarities of the thermalization process.
