Coincident fisson fragments were detected to study the complete capture reaction, /sup 40/Ar + /sup 238/U..-->../sup 278/110..-->..f, at E/sub c.m./ = 291 MeV (E/sub lab/ = 340 MeV). The detection system had a high efficiency to detect and subsequently veto events showing evidence of incomplete momentum transfer. The angular distribution of fission fragments was obtained between the center of mass angles of 119/sup 0/ and 164/sup 0/. The mass distributions of the fission fragments were also obtained for the angles. One non-coincident measurement made at theta/sub c.m./ = 43.7 confirmed the symmetry of the angular distribution about 90/sup 0/. The rotating liquid drop model parameters were extracted from the data. The RLDM shapes along with statistical fission models, when applied to all partial waves, fail to reproduce the angular distributions. The author interperets the angular distributions by applying statistical equilibrium models and RLDM shapes for the nonvanishing fission barrier partial waves and by assuming that the vanishing fission barrier partial wave contribution is given by 1/sintheta. A 1/sintheta distribution is expected for a system which has not reached complete statistical equilibrium and maintains a memory of its entrance channel, with the fission fragments being emitted in the reaction plane defined by the initial contact.
