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 3n
evaporation channels and the reactions ⁴⁵Sc+^246,248Cm in 3n and 4n channels, and the system ⁵¹V+²⁴⁴Pu in 3n channel.
