New isotope, Sg264, was identified using the U238(Si30, xn)Sg268-x reaction and excitation functions for Sg262-264 were measured. Sg264 decays by spontaneous fission with a half-life of 37-11+27 ms. The spontaneous fission branch for 0.9-s Sg263 was measured for the first time and found to be (138)%. Sg262 decays by spontaneous fission with a 15-3+5 ms half-life. Spontaneous fission partial half-life systematics are evaluated for even-even Sg isotopes from Sg258 through Sg266, spanning the transition region between the N=152,Z=100 and N=162,Z=108 deformed shells. 2006 The American Physical Society.
