Searching for effective pathways for the production of proton- and neutron-rich isotopes through an optimal combination of reaction mechanism and energy is one of the main driving forces behind experimental and theoretical nuclear reaction studies as well as for practical applications in nuclear transmutation of radioactive waste. We report on a study on incomplete fusion induced by deuteron, which contains one proton and one neutron with a weak binding energy and is easily broken up. This reaction study was achieved by measuring directly the cross sections for both proton and deuteron for $^{107}$ Pd at 50 MeV/u via inverse kinematics technique. The results provide direct experimental evidence for the onset of a cross-section enhancement at high energy, indicating the potential of incomplete fusion induced by loosely-bound nuclei for creating proton-rich isotopes and nuclear transmutation of radioactive waste.

We observed two -decay chains starting from $^{228}$ Pu in the reaction of $^{34}$ S+ $^{198}$ Pt, and the half-life was measured to be 1.1 $^{+2.6}_{-0.5}$ s for the first time. This contradicts the literature value of 4 ms as an upper limit, although the -decay energy agrees with each other. The present half-life follows the Geiger-Nuttall curve for even-even Pu isotopes, showing the dominant -decay branch. In this reaction, six decays of $^{228}$ Np were firstly observed. The average -particle energy was 709761 keV. The evaporation residue cross sections of $^{228}$ Pu, $^{228}$ Np and $^{225}$ U are reproduced by a statistical model calculation.
