AbstractThe convincing candidate event of the isotope of the 113th element, (278)113, and its daughter nuclei, (174)111 and (270)Mt, were observed, for the first time, in the Bi-209 + Zn-70 reaction at a beam energy of 349.0 MeV with a total dose of 1.7 x 10(19). Alpha decay energies and decay times of the candidates, (278)113, (214)111, and (270)Mt, were (11.68 +/- 0.04 MeV, 0.344 ms), (11.15 +/- 0.07 MeV, 9.26 ms), and (10.03 +/- 0.07 MeV, 7.16 ms), respectively. The production cross section of the isotope was deduced to be 55(-45)(+150) fb (10(-39) cm(2)).
