Intermediate-mass fragments (IMF) from the {sup 209}Bi+{sup 136}Xe reaction at {ital E}{sub lab}/{ital A}=28MeV have been measured in coincidence with other reaction products, using a highly efficient 4{pi} detector setup. Their emission patterns exhibit features consistent with dynamical fragmentation of a neck zone between the reaction partners, in addition to sequential statistical emission. In peripheral collisions with an average of 0.3 GeV of dissipated kinetic energy, the dynamical process accounts for 0.24 of the observed IMF multiplicity of 0.33. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.
