Descripción
The angular distributions 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 fragment angular anisotropies are 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 hindrance to complete
fusion at small collision energies increases due to the increase of
quasifission events and it is explained by the elongated shape of the
dinuclear system which is formed in collisions with small orientation
angles to the beam direction. An increase of the hindrance to complete
fusion at large beam energies is explained by the dependence of the
quasifission and intrinsic fusion barriers of dinuclear system on its
angular momentum. In this reaction the contributions of fusion-fission
and quasifission fragments are comparable.
