| Abstract
| - The discovery of the new chemical element with atomic number Z=117 is presented. The isotopes 293 117 and 294117 were produced in fusion reactions between 48Ca and 249Bk. The 249Bk was produced in the High Flux Isotope Reactor and chemically separated at Oak Ridge. Decay chains involving eleven new nuclei were identified by means of the Dubna Gas-Filled Recoil Separator. The measured decay properties show a strong rise of stability for superheavy nuclei toward N=184.The reaction 243Am+ 48Ca was studied at three energies. Twenty one decay chains of 288115 and one decay chain of 289115 were observed to confirm the earlier discoveries of Z=115 and 117.
