• The convincing candidate event of the isotope of the 113th element, ^<278>113, and its daughter nuclei, ^<274>111 and ^<270>Mt, were observed, for the first time, in the ^<209>Bi + ^<70>Zn reaction at a beam energy of 349.0MeV with a total dose of 1.7 × 10^<19>. Alpha decay energies and decay times of the candidates, ^<278>113, ^<274>111, and ^<270>Mt, were (11.68 ± 0.04MeV, 0.344ms), (11.15 ± 0.07MeV, 9.26ms), and (10.03 ± 0.07 MeV, 7.16ms), respectively. The production cross section of the isotope was deduced to be55^<+150>_<45> fb(10^<-39>cm^2).
