Abstract: A possible way to synthesize superheavy element (Z=117) by using 48Ca+249Bk reaction is studied with two step model. The fusion process is divided into two steps: the sticking process that the projectile approaches to the target to get contacted with the target by passing over the Coulomb barrier, and the formation process that the dinuclear system evolves from contact into compound nuclear state. Combined with the statistical evaporation model, the formation cross section of 297117 is calculated. The result shows that the residue for 3 neutron evaporation is 0.34 pb at excitation energy E*=31 MeV, which is detectable in laboratory.
