Abstract
New isotope, , was identified using the (, x) reaction and excitation functions for were measured. decays by spontaneous fission with a half-life of ms. The spontaneous fission branch for 0.9-s was measured for the first time and found to be (13±8)%. decays by spontaneous fission with a ms half-life. Spontaneous fission partial half-life systematics are evaluated for even-even Sg isotopes from through , spanning the transition region between the and deformed shells.
