Abstract
Two -decay chains starting from produced in the reaction of were observed, and the half-life was measured to be . The half-life follows the Geiger-Nuttall curve for even-even Pu isotopes, which shows that decay is the dominant decay mode. In addition, five -decay events of were observed for the first time. The evaporation residue cross sections of , , and are reproduced by a statistical model calculation.
