The superheavy nucleus 270Hs is expected to be a “double-magic” deformed nucleus. We have calculated its cross sections of evaporation residue for the reactions 248Cm(26Mg,4n)270Hs, 244Pu(30Si,4n)270Hs, 238U(36S,4n)270Hs and 226Ra(48Ca,4n)270Hs using a two-parameter Smoluchowski equation. It is found from our results that 226Ra(48Ca,4n)270Hs and 238U(36S,4n)270Hs are two optimal reactions for the synthesis of the superheavy nucleus 270Hs due to their large negative Q-values.
We have calculated its cross sections of the evaporation residue for the reactions 248Cm (26Mg, 4n) 270Hs, 244Pu (30Si, 4n) 270Hs, 238U (36S, 4n ) 270Hs and 226Ra (48Ca, 4n) 270Hs using a two-parameter Smoluchowski equation. It is found from our results that 226Ra (48Ca, 4n) 270Hs and 238U (36S, 4n) 270Hs are two optimal reactions for the synthesis of the superheavy nucleus 270Hs due to their large negative Q-values.
