ABSTRACT
Fragment mass distributions from neutron-induced fission of 232Th and 238U have been measured at quasi-monoenergetic neutron beam of the Louvain-la-Neuve cyclotron facility CYCLONE. The measurements have been carried out making use of a multi-section Frisch-gridded ionization chamber. The measurement technique as well as the data processing is described. Preliminary data on primary fragment mass yields are given for an incident neutron energy of 32.8 MeV.

    The results of experimental and theoretical studies of the deuteron-induced fission of 238U at Ed = 65 and 124 MeV are presented. The nucleon spectra measured in the coincidence with fission fragments were analyzed taking into account the direct (d, pf) and (d, nf) channels, pre-compound...

    On the base of modified trajectory calculations the shift of angular distribution of α-particles accompanied the reaction 235U(n,f) induced by cold polarized neutrons is evaluated. It was supposed that angular distribution shift is caused by the rotation of nuclear system before scission. The...
