The 244Pu(50Ti,xn)294−xLv reaction was investigated at Lawrence Berkeley National Laboratory’s 88-Inch Cyclotron. The experiment was aimed at the production of a superheavy element with Z ≥ 114 by irradiating an actinide target with a beam heavier than 48Ca. Produced Lv ions were separated from the unwanted beam and nuclear reaction products using the Berkeley Gas-filled Separator and implanted into a newly commissioned focal-plane detector system. Two decay chains were observed and assigned to the decay of 290Lv. The production cross section was measured to be σprod =0.44+0.58−0.28 pb at a center-of target center-of-mass energy of 220(3) MeV. This represents the first published measurement of the production of a superheavy element near the “island of stability,” with a beam of 50Ti and is an essential precursor in the pursuit of searching for new elements beyond Z = 118. |
