英文摘要We report on an attempt to produce and detect (268)Hs and (269)Hs in the nuclear fusion reaction Mg-25+Cm-248 using the gas phase chemistry apparatus COMPACT. No decay chains attributable to the decay of hassium isotopes were observed during the course of this experiment. From the nonobservation of (269)Hs we derive a cross section limit of 0.4 pb (63% confidence limit) for the reaction Cm-248(Mg-25,4n)(269)Hs at a center-of-target beam energy of 140 MeV. The evaluated cross section limit for the Cm-248(Mg-25,5n)(268)Hs reaction depends on the assumed half-life of unknown (268)Hs. Current systematics of the half-lives for even-even Hs isotopes suggests a value of 0.5 s, resulting in a cross section limit of 1.3 pb.
