The isotopic yields of Rb, In, and Cs from the 40--100 MeV proton-induced fission of /sup 233/U and /sup 235/U, and the isotopic yields of Ga from the 80 and 100 MeV proton-induced fission of /sup 233/U have been measured by on-line mass spectrometry. The yields have been normalized to the independent formation cross sections of selected isotopes measured radiochemically. Total numbers of neutrons emitted per fission event have been deduced from the centroids of the isotopic distributions. The equal charge displacement, minimum potential energy, and unchanged charge distribution mechanisms have been investigated. It is found that the charge-division mechanism is fragment-mass dependent, the minimum potential energy postulate being attributed to asymmetric fission events and the unchanged charge distribution postulate being attributed to near-symmetric fission events.
