In this paper the experimental data regarding 238-U fission at proton energy 660 MeV are presented and analyzed. The absolute values of 51 cross-sections of fragment production, in the range of mass numbers 7-70 amu, are obtained and evinced. Such fragments may be considered as a third particle accompanying two other fragments. The ternary fragment mass distribution may bring informations on the nucleon composition of the neck, and the high energy associated to the fissioning nucleus might provide an overlap between the ternary and binary fission, in the mass region of fission fragments 50-70 amu. Furthermore, the cross-section of 238-U ternary fission is determined, as well as the ratio for binary/ternary fission, in order to obtain new prominent data delving into the underlying fission mechanism concerning the proton-induced fission at intermediate energies.
