Complex fragments with 4 ⩽ Z ≲ 50 have been detected in the reactions of 139 La + 12 C and 27 Al at E / A = 14.7 and 18.0 MeV. From the measured angular distributions, the cross sections for the isotropic, target-like and projectile-like components were extracted. The roles of deep-inelastic, fast-fission, and incomplete fusion processes, and the statistical, compound nucleus emission of complex fragments are discussed.
