Abstract

The convincing candidate event of the isotope of the 113th element, ²⁷⁸113, and its daughter nuclei, ²⁷⁴111 and ²⁷⁰Mt, were observed, for the first time, in the ²⁰⁹Bi + ⁷⁰Zn reaction at a beam energy of 349.0 MeV with a total dose of 1.7 × 10¹⁹. Alpha decay energies and decay times of the candidates, ²⁷⁸113, ²⁷⁴111, and ²⁷⁰Mt, were (11.68 ± 0.04 MeV, 0.344 ms), (11.15 ± 0.07 MeV, 9.26ms), 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 cm²).
