DESCRIPTION:Speakers: Katsuhisa Nishio (Japan Atomic Energy Agency)\nThe M
 NT reaction allows us to produce many fissioning nuclei\, including neutro
 n-rich nuclei\, which cannot be populated by other reactions. Also\, excit
 ation energy of compound nucleus distributes widely. These properties are 
 used to obtain fission-fragment mass distribution (FFMDs) for many nuclide
 s as well as their excitation-energy dependence [1\,2\,3]. The experiments
  were carried out at the JAEA tandem facility using $^{18}$O beam and vari
 ous radioactive target nuclei. From the data\, the probability of each mul
 ti-chance fission (fission after neutron emission) was quantified for the 
 first time [4\,5]. From the threshold of the excitation function of fissio
 n probably\, fission barrier height was derived [6]\, one of the key obser
 vables to verify fission models.\n\nOur setup for MNT-induced fission allo
 ws us to obtain data for MNT mechanism itself. From the fission-fragment a
 ngular distribution relative to the rotational axis\, we have determined t
 he average angular momentum for each MNT channel [7]. The value is useful 
 to determine the survival probability of compound nucleus to derive the cr
 oss sections of neutron-rich evaporation residues generated in MNT reactio
 ns.\n\nReference\n\n[1] R. Leguillon et al.\, Phys. Lett. B 761\, 125 (201
