Fission-fragment mass distributions were measured for $$^{237-240}$$U, $$^{239-242}$$Np and $$^{241-244}$$Pu populated in the excitation-energy range from 10 to 60 MeV by multi-nucleon transfer channels in the reaction $$^{18}$$O + $$^{238}$$U at the JAEA tandem facility. Among them, the data for $$^{240}$$U and $$^{240,241,242}$$Np were observed for the first time. It was found that the mass distributions for all the studied nuclides maintain a double-humped shape up to the highest measured energy in contrast to expectations of predominantly symmetric fission due to the washing out of nuclear shell effects. From a comparison with the dynamical calculation based on the fluctuation-dissipation model, this behavior of the mass distributions was unambiguously attributed to the effect of multi-chance fission.

The Coulomb barrier distribution between heavy nuclei is important quantity to investigate the effect of quantum couplings of nuclear vibration and nucleon transfer to nucleus-nucleus interaction. We obtained the barrier distributions of lead-based fusion reactions of $$^{48}$$Ti, $$^{54}$$Cr, $$^{56}$$Fe, $$^{64}$$Ni, $$^{70}$$Zn, $$^{76}$$Ge, and $$^{86}$$Kr projectiles on $$^{208}$$Pb by means of the measurements of the quasi-elastic cross sections at backward scattering angles. The obtained positions and widths of the barrier distributions are compared with a calculation taking account of the channel couplings. The effect of the nuclear deformation on reaction process was also investigated by means of the measurements of product mass distributions for the systems of $$^{30}$$Si, $$^{36}$$S, $$^{40}$$Ar projectiles on $$^{238}$$U. We found that the collision at polar side gives rise to quasi-fission, where an asymmetric fission is dominant.

The excitation function of the $$^8$$Li(d,t)$$^7$$Li reaction was directly measured using $$^8$$Li beams at E$$_{mathrm{cm}}$$ = 0.3, 0.4, 0.5, 0.7, 0.8, 1.0, 1.1, and 1.2 MeV with CD$$_2$$ targets. The beam energies covered the Gamow peaks for 1$$sim$$3$$times$$10$$^9$$ K. Large cross sections were observed at around E$$_{mathrm{cm}}$$ = 0.8 MeV, implying a resonance state located at 22.4 MeV in $$^{10}$$Be. The present astrophysical reaction rate is higher in one order magnitude than the presently adopted rate at around 1$$times$$10$$^9$$ K.
