摘 要：In the Institute of Physical and Chemical Research(RIKEN),using high intensity heavy ion beams from the R/KEN Linear Accelerator,productions and decays of isotopes of the heaviest elements have been investigated by using the gas-filled recoil separator,*** isotopes studied were Hs,Ds,Rg,112,and 113,*** on the observed decay chains consisting of consecutive alpha decays connected to the previously known alpha decays or spontaneous fissions,assignments of the initially produced isotopes were *** data with the atomic number from 108 to 112,agree well with the data previously *** production cross section of the isotope 113 of the 113th element have reached around 32 tl0 which shows the simple decrease of the cross section with the increase of the atomic number. The isotopes were produced,for the first time in the In evaporation channel from heavy-ion induced fusion reaction.
