Abstract: The fusion-evaporation reaction Pu244(Ca48,3-4n)114288,289 was studied at the new gas-filled recoil separator TASCA. Thirteen correlated decay chains were observed and assigned to the production and decay of 114288,289. At a compound nucleus excitation energy of E*=39.8-43.9MeV, the 4n evaporation channel cross section was 9.8-3.1+3.9pb. At E*=36.1-39.5MeV, that of the 3n evaporation channel was 8.0-4.5+7.4pb. In one of the 3n evaporation channel decay chains, a previously unobserved α branch in Ds281 was observed (probability to be of random origin from background: 0.1%). This α decay populated the new nucleus Hs277, which decayed by spontaneous fission after a lifetime of 4.5 ms. © 2010 The American Physical Society.
