Possible Way to Synthesize Superheavy Element Z =117
Possible Way to Synthesize Superheavy Element Z=117

Within the framework of the dinuclear system model, the production of superheavy element Z=117 in possible projectile--target combinations is analysed systematically. The calculated results show that the production cross sections are strongly dependent on the reaction systems. Optimal combinations, corresponding excitation energies and evaporation channels are proposed, such as the isotopes 248,249Bk in 48Ca induced reactions in 3nevaporation channels and the reactions 45Sc+246,248Cm in 3n and 4n channels, and the system 51V+244Pu in 3n channel.
