Abstract
The decay properties of and , and the dependence of their production cross sections on the excitation energies of the compound nucleus, , have been measured in the (, ) reaction. These isotopes of element 116 are the decay daughters of element 118 isotopes, which are produced via the reaction. We performed the element 118 experiment at two projectile energies, corresponding to compound nucleus excitation energies of and MeV. During an irradiation with a total beam dose of projectiles, three similar decay chains consisting of two or three consecutive decays and terminated by a spontaneous fission (SF) with high total kinetic energy of about 230 MeV were observed. The three decay chains originated from the even-even isotope ( MeV, ms) produced in the -evaporation channel of the reaction with a maximum cross section of pb.
