The electrofission cross section for /sup 234/U from 5.5 to 25.4 MeV has been measured. From a combined analysis of it and the previously measured photofission cross section, using virtual-photon spectra calculated in the distorted-wave Born approximation, the E2 photofission cross section has been determined. Parameters of the fission-decay branch of the giant quadrupole resonance for this nucleus have been obtained. A comparison of the E2 and E1 integrated photofission cross sections for the even uranium isotopes shows that the E1 fission channel increases in strength more rapidly with fissility than does the E2 channel.
