The angular distribution of ﬁssion fragments for the 32S+184W reaction at center-of-mass energies of 118.8, 123.1, 127.3, 131.5, 135.8, 141.1 and 144.4 MeV were measured. The experimental ﬁssion excitation function is obtained. The fragment angular anisotropy is found by extrapolating the ﬁssion angular distributions. The measured ﬁssion cross sections are decomposed into fusion-ﬁssion, quasiﬁssion and fast-ﬁssion contributions by the dinuclear system model. The total evaporation residue and fusion-ﬁssion excitation functions are calculated in the framework of the advanced statistical model.
