A model-independent multipole analysis of /sup 238/U(e,e'f) coincidence data, taken at four momentum transfers (0.2less than or equal toq/sub eff/less than or equal to0.7 fm/sup -1/; ..omega.. = 4--22 MeV) yields both E1, E2/E0, and E3 form factors and strength distributions. The E2/E0 strength distribution in the fission channel shows two distinct bumps centered at ..omega..approx. =10 and 14 MeV, exhausting up to 12 MeV (19 +- 2)% of the isoscalar E2 sum rule. The extracted form factors can be described within a hydrodynamical model by use of parameters c/sub tr//c/sub 0/ = 1.2 and 1.0 for E1 and E2, respectively.
