Abstract
We present a review of the recent progress of theoretical models on the description of the superheavy nucleus formation in heavy ion collisions. Two sorts of reactions that are the fusionevaporation mechanism and the massive damped collisions to produce superheavy nuclei are discussed. Problems and further improvements of the capture of colliding partners, the formation of compound nucleus and the deexcitation process are pointed out. Possible combinations for the synthesis of the superheavy nuclei in between the roducts of the cold fusion and 48Ca induced reactions are proposed by the calculations based on the dinuclear system model and also compared with other
approaches. The synthesis of neutronrich heavy isotopes near subshell closure N=162 via transfer reactions in the damped collisions of two actinides and the influence of shell closure on the production of heavy isotopes are investigated. Prospective possibility to reach superheavy nuclei near N=184 via neutronrich radioactive beams of high intensity in the future is discussed.
